Product Description:
The PMB33F-20200-00 brushless servomotor is produced by Pacific Scientific within the PMB Brushless Servomotors series. Designed for closed-loop industrial automation, this NEMA-frame actuator converts command currents into controlled torque and velocity for indexing tables, packaging lines, and coordinated robot joints. Its brushless design supports accurate motion control while reducing wear associated with mechanical commutation components.
With a frame classified as NEMA Size 34, the motor uses mounting dimensions common to many stepper and servo packages. The electromagnetic stack uses a stack-length multiple of 3, which increases available torque without changing the overall footprint. At a 240 VAC bus, the winding reaches a nominal stall current of 11.0 ARMS, so the selected drive must support that continuous current level during holding conditions. Rotor position is returned through a Resolver, providing analog sine-cosine feedback that remains stable in electrically noisy environments and at elevated temperatures. Power, feedback, and protective earth connections leave the housing as flying leads with MS connectors, allowing secure mate-and-lock connections during installation.
The output shaft uses a square key, providing positive torque transmission to pulleys or couplings while helping prevent slip during reversals. Because the unit is supplied as a standard motor, it uses the normal winding and mechanical configuration for this model. The design is associated with Pacific Scientific PMB motors that share common electrical and mechanical layout practices across the line. Its inclusion in the PMB Brushless Servomotors series means the motor follows the same general thermal approach and resolver interface used within that line. This unit remains suitable for multi-axis industrial equipment where compact mounting, analog feedback, and keyed shaft transmission are required.
