33VM52-000-29

33VM52-000-29 is a Pacific Scientific PMDC servomotor in the Low Inertia PMDC Servomotors series. It uses Alnico V-7 magnets to produce the motor’s permanent magnetic field. The motor is rated for a 24 VDC supply and an RMS current of 6.4 A, establishing its nominal electrical operating requirements. Its terminal resistance is 0.85 Ω, which indicates the resistance across the motor terminals and affects current flow and electrical losses.

The torque constant is 5.9 oz-in/A, indicating the amount of torque produced for each ampere of current. Rotor inertia is 0.00043 oz-in-sec², supporting rapid changes in rotational speed and direction in servo applications. The motor does not use forced-air cooling, so thermal management depends on natural convection and heat transfer through the motor housing and mounting structure.
