Product Description:

The PWM3652-5458-4 is a direct-current motor produced by Pacific Scientific within the PWM Brushed Treadmill Motors series. This motor is intended for speed-controlled belt or roller drives in automated equipment, where a DC source is chopped by a pulse-width-modulated controller to regulate torque and speed. By converting electrical energy into rotational motion on a permanent-magnet field, it offers a compact solution for continuous material transport or positioning tasks on the factory floor.

The armature can draw up to 12 A under rated conditions, indicating the current that the associated drive must be able to deliver without excessive voltage sag. A continuous duty classification confirms that the winding temperature rise is managed for nonstop operation rather than intermittent bursts. The winding set is housed in an open frame, so installation must provide external airflow for heat removal and keep contaminants within acceptable limits. Its magnetic circuit uses a permanent-magnet design, which eliminates field coils and simplifies power wiring while maintaining stable flux. At rated load, the motor produces 3.2 HP, which provides a reference for mechanical sizing of the driven element and the required torsional coupling.

The motor has an IP20 rating, which permits finger-safe access but does not protect against sprayed liquids or dust ingress. When fully energized, the rotor stabilizes near 3400 rpm, a speed suitable for direct belt drives or for gear reduction when higher torque is needed. The motor requires 220 VDC, so the drive or power supply must deliver a matching DC output. Protective earth is established through the motor case, and the electrical system should reference this connection to avoid ground loops. For installations that use a form factor of 1, the average-to-RMS voltage ratio remains unity, which simplifies thermal estimates for the commutator and brushes.
