Product Description:

The 33VM62-100-4 permanent-magnet DC servomotor is produced by Pacific Scientific as part of the Low Inertia PMDC Servomotors series. Designed for closed-loop industrial axes, the unit supplies quick torque changes while keeping armature inertia low, allowing pick-and-place tables, dispensers, and material-handling slides to meet cycle-time targets without overshoot. Its low-inertia armature couples directly to light loads, converting drive current into precise rotation for automated positioning tasks across packaging, semiconductor, and small robotics lines.

Brush maintenance is simplified because the brush assemblies are specified as field replaceable, allowing replacement without full disassembly. The commutation pair uses carbon brushes, a material choice that balances conductivity with controlled wear on the commutator. Thermal management relies on air inlet and outlet passages with no internal baffles. The unobstructed path keeps frame temperature within limits during continuous duty. Rotor flux is supplied by Alnico V-7 magnets whose high residual induction supports repeatable torque generation at low speeds. The frame also provides standard encoder mounting, allowing incremental or absolute feedback devices to be installed as needed.

The mechanical core employs a hollow rotor, trimming rotational mass so acceleration profiles remain short even when the motor is coupled to compliant loads. Control accessories are intentionally minimal: there is no analog tachometer attached, and there is no optical encoder attached, so feedback hardware can be selected to suit the application. This arrangement leaves sensor choice open while keeping the motor adaptable to different drive signal requirements. Replacement brush kits slide into the motor’s service ports during routine maintenance.
