Description
The 1092090180 is the 37 kW motor assembly for Atlas Copco oil-injected screw compressors on a 400 V, 50 Hz supply. It is the drive unit that turns electrical power into the rotor speed the compressor element needs, and it is built as a two-pole machine in the high-speed class.
A drive motor is ordered by number, by type and by nameplate. The 1092090180 is the record a planner carries when a 37 kW drive line has to be renewed, and the data below is the data the workshop matches against the machine.
What the 1092090180 Motor Assembly Is
The 1092090180 is listed as a motor assembly rated 37 kW on a 400 V, 50 Hz supply. The assembly is a complete drive unit: the stator and the rotor, the housing around them, the shaft end that enters the coupling and the flange that bolts it to the compressor.
The Part Record and Its Number
The item record names the part under the number 1092090180, with Motor Assembly 37 kW 400 V 50 Hz as the description of the item. The number is the line the order travels under, so the same unit is picked whether the workshop orders by code or by description.
The 37 kW figure puts the 1092090180 in the class of Atlas Copco oil-injected screw compressors that includes the GA 37 machine. The machine record confirms the fitment, because a motor is matched by type, mounting and supply rather than by output alone.
What an Assembly Covers
The 1092090180 is listed as a motor assembly rather than a bare motor. The unit arrives ready to be mounted, so the drive line is restored by changing the complete motor.
The assembly measures 101.5 × 76.5 × 92 cm and weighs 425 kg as supplied, and the net weight recorded for the motor itself is 278 kg. Both figures are used when the change is planned.
A Two-Pole Motor in the 37 kW Class
The 1092090180 is a two-pole, three-phase induction motor. Its nameplate speed is 2960 r/min, which is the loaded speed of the two-pole class on a 50 Hz network, and its rated current is 65.2 A.
The motor type on the nameplate is YXLA200L2-2, and the code opens with the frame size 200L and closes with the pole count 2.
Synchronous Speed and Slip
A two-pole motor on a 50 Hz supply has a synchronous speed of 3000 r/min. The 1092090180 runs at 2960 r/min under load, and the difference of 40 r/min is the slip of the induction machine, 1.3 % of the synchronous figure.
Slip is what lets the rotor develop torque, and a small slip is the mark of a motor that holds its speed under changing load.
Why the High-Speed Class Suits a Direct Drive
A compressor element built to run close to 3000 r/min is driven straight from a two-pole motor, with a coupling between the two shafts and no belt or gear ratio in between. The 1092090180 belongs to that arrangement: the flange face carries the motor on the element housing and the shafts meet in the coupling.
The direct link keeps the drive simple, and it puts the alignment of the two shafts at the centre of the installation. Clean and true flange faces keep the line straight and the vibration low, which is what the mounting of the 1092090180 is built for.
Nameplate Data and What It Tells the Workshop
The nameplate is what a workshop reads before an order is placed and again before the motor is started. The plate of the 1092090180 carries the type, the output, the supply, the speed, the current and the class data of the winding system.
The Electrical Ratings on the Plate
The 1092090180 is rated 37 kW at 400 V, 50 Hz, with a rated current of 65.2 A and a starting current of 75.0 A. The type is YXLA200L2-2 and the rated speed is 2960 r/min.
Those values decide whether a motor belongs on a machine: output, voltage and frequency have to agree with the supply and the load.
Efficiency Class IE2 at 92.8 %
The efficiency class recorded for the 1092090180 is IE2 at 92.8 %. Efficiency class is a fixed property of the design: it is set by how much active material sits in the core and the windings, and it does not change with the running hours of the machine.
What changes in service is how much of that figure the motor actually delivers. An assembly that is aligned, clean and cool holds its plate value, and one with a worn bearing or a blocked cooling path does not.
The Delta Connection
The plate records the winding connection of the 1092090180 as delta. In a delta connection the three windings are joined end to end and the supply is applied across each pair of terminals, which is the arrangement three-phase motors of this size use.
The connection is part of the installation rather than a detail of the order. The link bars in the terminal box are set to match the plate before the supply is switched on.
Working Margin: Service Factor and Ambient
Two figures on the plate of the 1092090180 describe the margin the motor carries beyond its rated output: the service factor and the ambient temperature it is built for.
Service Factor 1.15
The service factor of the 1092090180 is 1.15. A service factor above 1.0 means the motor is built to carry a load above its rated output without going past the thermal limit of its insulation, and 1.15 gives a margin of 15 %.
In a compressor that figure covers the moments when the machine works harder than its steady point. The margin is there to be used, and it is not a reason to run the 1092090180 above its rated output.
Ambient 46 °C and Insulation Class F
The ambient rating of the 1092090180 is 46 °C and its insulation class is F. The ambient figure is the air temperature the motor is built for, and the insulation class is the thermal class of the winding system.
A warm compressor package raises the air the motor draws through, and class F insulation gives the winding the headroom to work in that air at the rated load.
Frame, Enclosure and Protection
The mechanical side of the 1092090180 is described by its frame, its enclosure and its protection class. Those three decide how the motor is mounted, how it is cooled and what it keeps out.
The 200L Frame
The 1092090180 is built on the 200L frame, the housing that holds the stator, the rotor and the bearings in line. The frame carries the mass of the machine and holds the air gap even across long running hours.
The frame also sets the footprint and the shaft end of the motor. Because the 1092090180 is a flanged assembly, the frame face is the joint that carries the motor on the compressor.
IP55 Protection
The protection class of the 1092090180 is IP55. The code has two parts: the first digit covers solid objects and the second covers water, and a 5 in each position describes a dust-protected and jet-protected enclosure.
That class suits a compressor room, where dust is always present and washing down is normal work. It protects the windings and the bearings inside the 1092090180 from what the room throws at them.
Installation and Commissioning Notes
The 1092090180 is a 425 kg assembly, so the change is planned around lifting and handling before anything is unbolted. The machine is stopped and isolated, and the motor is brought to the flange with the shaft lined up for the coupling.
Before the Motor Is Bolted Up
The flange face is the joint that decides how the drive runs. It is cleaned and checked for true before the 1092090180 is offered up, and the coupling is inspected for wear while the drive line is open.
The mounting bolts are then made up evenly, so the flange is drawn down square rather than pulled to one side.
Supply and Connection Checks
The supply is confirmed against the plate of the 1092090180: 400 V at 50 Hz, three-phase, with the winding connected in delta. The terminal box is checked for the link bar setting and for clean, tight terminations.
The protective device is set for the rated current of 65.2 A, and the insulation of the circuit is checked before the motor is energised.
First Run and Running Checks
The 1092090180 is turned over on a short no-load run to confirm that it spins free and in the right direction. The machine is then loaded and the running readings are taken.
The readings to watch are current, temperature and vibration. Current follows the load, temperature follows the cooling, and vibration follows the alignment and the bearings. A steady set of readings is the sign that the 1092090180 is sitting on its ratings.
Ordering the 1092090180 Through Seadweer
A drive motor is ordered by record and by plate, because two motors of the same output can differ in type, frame, supply and winding connection. The ordering routine of the 1092090180 is built around that fact.
The Machine Record Check
Send Seadweer your compressor model and serial number, and the team checks the machine record against the 1092090180 before the quotation is issued. If your unit carries a different motor number or a different flange, the same check resolves it and the order is placed on the number that fits your machine.
What the Quotation Repeats
The quotation repeats the item data of the 1092090180: the description, the motor type, the electrical ratings and the physical figures. One confirmation covers the whole assembly, so the workshop can plan the change without a second enquiry.

Daniel Mwangi –
Our 37 kW machine came due for a drive motor, and the 1092090180 was the number on the unit record. The team checked the type, the 400 V ratings and the frame against the nameplate we sent over, so the motor arrived with the mounting and the winding arrangement our machine runs. It went back into service in the planned window and has held its readings since.
