Product Description:

The PMB33E-10116-01 brushless servomotor is produced by Pacific Scientific and belongs to the PMB Brushless Servomotors series. In industrial automation, it converts electric power into tightly regulated rotary motion, allowing positioning stages, indexing tables, and material-handling axes to maintain commanded speed and accuracy during duty cycles. This operating role suits machines that need repeatable starts, stops, and speed changes under varying loads.

With a frame classified as NEMA Size 34, the motor fits the common 3.4-inch square mounting pattern. At 240 VAC, the drive must supply a continuous 7.4 ARMS nominal stall current, indicating the thermal load the winding can withstand while the rotor is blocked. High-resolution feedback is available from an encoder that outputs 4096 ppr, which lets the controller resolve motion to less than 0.1° per count. The feedback device is a digital encoder with commutation, so the same sensor also provides phase information needed for electronic commutation and removes the need for separate Hall elements. Torque density is influenced by the laminated core that uses a Stack Length Multiple of 3, meaning three standard magnet stacks are combined to reach the designated electromagnetic length.

Electrical terminations exit the housing as flying leads with AMP connectors, allowing direct connection to cabinet harnesses without an added motor connector. The output shaft is round, a geometry compatible with clamp or collet couplings when low backlash is required. For light washdown or oil-mist environments, an optional Shaft Seal can be installed to protect the front bearing against fluid ingress. The motor is part of the PMB Series Brushless Servomotor line and can be paired with matched Pacific Scientific servo drives.
