Product Description:
The 33VM52-000-29 is a permanent-magnet DC servomotor from Pacific Scientific and belongs to the Low Inertia PMDC Servomotors series. It is intended for industrial automation where a low-inertia shaft must follow commanded speed or position quickly. The motor’s compact frame and direct-current supply make it suitable for machines that need fast reversals while staying within a low-voltage power architecture. Its purpose is to convert electrical energy into controlled rotary motion for closed-loop axes. In this type of application, quick response is useful on indexing, positioning, and reversing duties where shaft speed must change without excessive lag.
It is engineered for a supply of 24 VDC, and at this voltage the armature draws a continuous 6.4 A RMS. With a torque constant of 5.9 oz-in/A, the motor develops nearly six ounce-inches of torque per ampere, which helps match the drive amplifier to steady-state load demand. The terminal resistance is 0.85 Ω, so resistive heating rises with current and must be considered when evaluating thermal limits and conductor sizing inside a cabinet. Because the frame uses no forced-air cooling, installation must allow free airflow or conductive heat paths to keep winding temperatures within rating. The low-voltage DC input also suits machines that distribute DC power directly to motion components instead of using a separate AC motor stage.
Dynamic behavior is set by the rotor’s 0.00043 oz-in-sec² inertia, which reduces the torque needed to change speed and helps limit overshoot in position loops. Magnetic flux is established by an Alnico V-7 permanent magnet set that resists demagnetization and temperature drift. The unit is classified as a PMDC Servomotor, and it is manufactured by Pacific Scientific. This motor style is commonly used where stable magnet strength and quick acceleration are important during repeated motion cycles.
