Product Description:

The PMB33F-20101-00 is a brushless servomotor manufactured by Pacific Scientific and assigned to the PMB Brushless Servomotors series. It is intended for closed-loop motion axes where rapid acceleration, precise positioning, and continuous duty are required in material handling cells, pick-and-place gantries, or small tooling stations. The motor’s permanent-magnet rotor works with an external amplifier so commanded current translates directly into proportional torque, enabling deterministic speed and position control inside automated equipment. This arrangement also supports smooth low-speed motion and repeatable indexing in automated machinery.

Within the PMB Brushless Servomotors series, this motor uses a NEMA Size 34 frame, so it fits mounting patterns commonly used for similarly sized motion components. The winding supports a nominal stall current of 11.0 ARMS at 240 Vac, allowing the motor to produce holding torque at zero speed when the drive is properly regulated. Power entry is provided through flying leads with AMP connectors, which simplifies connection to the controller without requiring a circular plug interface. Rotor position and phase reference are supplied by an integrated Hall sensor, which provides logic-level commutation signals and supports stable alignment during startup and low-speed operation.

The square key shaft provides a positive mechanical drive interface for pulleys, gears, or rigid couplings without relying only on clamping force. A lamination stack length multiple of 3 increases active magnetic length while keeping the same basic frame cross-section. This unit is supplied as a standard motor, making it suitable for general catalog applications without a custom configuration. Documentation and accessory compatibility are supported by Pacific Scientific, helping the motor remain consistent with the rest of the product line during integration and service.
