Product Description:
The 2VM52-000-11 is a permanent-magnet DC servo motor manufactured by Pacific Scientific and offered within the Low Inertia PMDC Servomotors series. As a low-inertia actuator, it is built to deliver fast acceleration and precise speed regulation for pick-and-place arms, indexing tables, and other motion axes that demand tight following of command profiles in industrial automation environments. Its permanent-magnet design eliminates field windings, which further lowers inertia and reduces electrical losses. The motor is a PMDC servo motor and is intended for operation with external drives that control armature voltage.
Mechanical service life is supported by ball bearings on both ends of the shaft, and the energizing elements use carbon brushes that ride on a slotted commutator. Those brushes are field-replaceable, allowing service without removing the motor from the machine. Torque production comes from a classic brushed commutation system that switches armature current mechanically, while magnetic flux is supplied by Alnico V-7 permanent magnets that maintain stable field strength over a wide temperature range. The motor is supplied without an analog tachometer and without an optical encoder, so speed or position feedback must be provided by external sensors in the drive system.
The internal armature uses a basket-wound configuration and a hollow rotor profile; together these features remove unnecessary rotating mass and keep inertia low for rapid dynamic response. The copper winding assembly is carried on a shaft-mounted commutator, so the commutator rotates with the shaft and helps maintain brush alignment during operation. The motor has no dedicated cooling provision, so the housing relies solely on ambient airflow and conduction to dissipate losses. The design also eliminates rotating iron to reduce cogging torque, keeping the envelope compact for tight mounting spaces.
