Product Description:

The 33VM62-200-1 is a permanent-magnet DC servomotor manufactured by Pacific Scientific within the Low Inertia PMDC Servomotors series. It is used in industrial automation where fast acceleration and accurate position control are needed, such as indexing tables or pick-and-place axes. The low rotor inertia lets the drive change speed quickly with minimal overshoot, and the permanent-magnet field eliminates separate excitation, reducing control complexity. Mounting dimensions on both faces make the unit suitable for direct coupling to gearheads or frameless assemblies inside compact machinery.

This servomotor occupies 2.97 in of body length measured from the mounting face, so it fits into shallow enclosures. Two cooling tubes are embedded at a 45° angle relative to the stator bore; this orientation directs coolant across the hottest winding zones for uniform temperature. With a tube count of 2, liquid or forced-air circuits can be configured in parallel to reduce pressure drop. The circular front flange has a reference diameter of 3.820 in, establishing the bolt circle that secures the motor to a gearbox or fixture. From the mounting plane to the end of the front housing, the motor projects only 1.825 in ±0.020, leaving space for couplings or encoders inside confined panels.

The pilot on the front face guides centering hardware with a reference diameter of 1.604 in, maintaining concentricity between the motor shaft and downstream components. Power is delivered through a ground and polished output shaft measuring 0.3745 in +0/-0.0005 in diameter, supporting clamp or keyed attachments without excessive backlash. A secondary rear shaft of 0.248 in +0.001/-0 diameter is available for feedback devices or manual rotation during setup. That rear journal extends 0.625 in ±0.020 beyond the mounting surface, providing length for a tachometer sleeve while still clearing most cabinet walls.
