Drive Motor 1635601801
Product Description
The 1635601801 Atlas Copco air compressor motor is the genuine main drive motor built for the GA family of oil-injected rotary screw compressors. It turns electrical power into the rotational energy that spins the screw element and builds plant air. Spec this motor wrong and the whole compressor line suffers. The genuine 1635601801 Atlas Copco air compressor motor is engineered to the original drawings. It is tested on the original bench and matched to the compressor controller. Order the correct motor for your machine and keep uptime high.
Product Overview
Every GA compressor needs a motor that starts hard, runs cool, and stops only for service. The 1635601801 sits at the front of the compressor, behind the cooler group, driving the rotor set. It is not a standard off-the-shelf part. It is a precision assembly balanced for the exact speed and load of the screw element.
The motor carries the full electrical load of compression. On a 37 kW package it pulls close to 40 kW at the input. On larger frames the current is higher still. A weak winding or a poor bearing here drops efficiency across the whole site. That is why the original design matters.
Atlas Copco builds these motors to a tight tolerance. The rotor is balanced, the stator is wound for the rated supply, and the shaft is machined to seat the original coupling. Fit the wrong assembly and you chase vibration, heat, and trips for the life of the machine.
Technical Specifications of the 1635601801 Atlas Copco Motor
The table below shows the identity facts confirmed for this genuine part. Exact electrical ratings vary by compressor model, so confirm them against your nameplate before you order.
| Attribute | Value |
|---|---|
| Part number | 1635601801 |
| Brand | Atlas Copco |
| Component | Main electric drive motor |
| Application | Oil-injected rotary screw air compressor (GA family) |
| Motor type | IE4 interior permanent magnet (iPM) on VSD+ variants |
| Cooling | TEFC; oil-cooled option on selected VSD+ models |
| Ingress protection | IP66 on oil-cooled drive motors |
| Standards | ISO 9001, ISO 14001, ISO 1217 |
| Supersession | None documented for this number |
Because the exact kW, voltage, and frequency depend on the compressor model, use the checklist below. It tells you what to confirm and why each line protects your machine.
| Confirm before ordering | Why it matters |
|---|---|
| Supply voltage and frequency | The winding is wound for a fixed supply. A wrong supply burns the insulation. |
| Rated power in kW | Frame size and shaft must match the compressor package and coupling. |
| Mounting and flange type | The motor must bolt onto the original foot or flange without shimming. |
| Encoder or feedback type | VSD models need the right resolver to talk to the drive. |
| Shaft dimensions | The coupling must seat without machining or modification. |
How the Drive Motor Works
A three-phase motor is a simple idea with tight engineering. Current in the stator coils makes a rotating magnetic field. That field pulls the rotor around. The rotor shaft leaves the motor and enters the compressor element.
On a fixed-speed GA, the motor runs at line frequency and the compressor holds a set pressure band. On a VSD+ model, the drive varies the frequency. The motor speeds up and slows down to follow air demand. That is where the iPM rotor earns its keep. It holds high efficiency across a wide speed range.
Cooling is the quiet hero. The motor sheds heat through its frame and fan, or through the compressor oil on oil-cooled types. Keep that path clear and the windings last for years. Block it and the insulation ages fast.
The controller watches temperature, current, and vibration. It trims output to protect the motor. A genuine motor speaks the same language as the controller, because both came from the same design team.
Installation, Maintenance and Troubleshooting
Installation
Fit the motor on a clean, flat footprint. Check the coupling alignment with a dial gauge before you torque the feet. A few thousandths of offset here becomes a hot bearing in a month. Torque every bolt to the manual. Do not guess. The feet, the terminal box, and the coupling guard all have a spec. Tight is not the same as correct.
Maintenance
Grease the bearings on the service schedule, not on a hunch. Too little and the race wears. Too much and the grease churns and heats. A fresh tube of the right grease beats a full rebuild later. Inspect the terminal box each service. Loose lugs arc and burn. Look for discoloration, smell for ozone, and check the seals. The box should stay dry even in a damp plant. Listen to the motor. A healthy unit has a steady hum. A rising whine or a knocking beat means something moved. Catch it early and you change a bearing, not a motor.
Troubleshooting
Overheating is the most common call. First check the cooling path. A clogged cooler, a failed fan, or blocked vents raise winding temperature within minutes. Clear the path before you blame the motor. Trips on start usually point to the supply or the load. Verify the voltage, the phase order, and the coupling freedom. A seized element loads the motor past its rating and the protection drops out. Vibration that grows over time often means a bearing. Pull the reading, compare it to the last service, and plan the change. Running on a bad bearing lets the rotor touch the stator, and that is a bad day for production. High current with normal load suggests winding damage or a tight mechanical link. Megger the windings and spin the shaft by hand. Either test points straight at the cause. Noise from the drive on VSD models can be a feedback fault. Confirm the encoder line and the parameter set. A genuine motor ships with the right feedback for the controller. Order the 1635601801 Atlas Copco air compressor motor through your Atlas Copco channel and confirm the rating from your machine nameplate. The right motor, fitted right, keeps your GA compressor making air.
FAQ
1
Which compressor models use the 1635601801 motor?
This motor serves the GA family of oil-injected rotary screw compressors. The exact frame fits a specific kW range, so match the number to your model plate. Your Atlas Copco dealer can confirm the precise fitment from the serial number.
2
How do I confirm this motor fits my machine?
Read the motor nameplate and the compressor data plate. Compare voltage, frequency, kW, and flange type to the checklist in the specifications section. When in doubt, give the serial number to Atlas Copco and let them verify the link.
3
Is the motor IE4 or a standard efficiency type?
GA VSD+ packages use IE4 interior permanent magnet motors for the efficiency gain. Fixed-speed frames may use a different class. The genuine part is always the class the original machine was designed around, so it meets the published rating.
4
Can the motor be repaired, or must it be replaced?
Small faults like a bearing or a seal are rebuildable by a qualified winder. Winding or rotor damage usually points to replacement. A genuine spare gets you back to original performance without a re-engineered guess.
5
What causes a motor to fail early?
Heat, moisture, and load. A blocked cooler, a damp terminal box, or a seized coupling each pushes the motor past its design. Follow the service plan, keep the cooling path open, and most motors reach their full life.
6
Does the motor include the encoder for VSD control?
On VSD+ variants the feedback device is part of the drive train. Confirm the exact type from the specification checklist, because the controller must read the right signal. Atlas Copco supplies the matching feedback for the genuine motor.
