Product Description:

Pacific Scientific produces the PMB33C-20114-00 as part of its PMB Brushless Servomotors series. This servomotor converts electrical energy into controlled rotary motion for positioning tasks in automated machinery, packaging lines, and electronic assembly systems. It is driven by a three-phase inverter and relies on closed-loop feedback to maintain torque and speed accuracy during start, stop, and rapid direction changes. Its general configuration suits automated axes that need repeatable response without adding unnecessary mechanical complexity.

The motor frame follows the NEMA Size 34 standard, so it shares mounting dimensions with other 3.4-inch square motors used in U.S. automation panels. A nominal stall current of 3.8 ARMS at 240 VAC is the continuous current the drive must supply when the rotor is locked. Position feedback comes from a 2048 ppr incremental encoder, allowing the controller to track shaft movement with fine resolution for servo loops. The unit uses a Digital Encoder with commutation, so encoder feedback and commutation signals are handled in one arrangement. Power conductors exit as Flying leads with AMP connectors, permitting quick crimp-style terminations without a circular connector shell. This layout helps keep installation straightforward where compact motor connections are preferred.

A keyed transmission interface is supplied through a Square Key shaft so couplings can transfer torque without slip under changing load. The electromagnetic package uses a stack length multiple of 3, which increases active motor length within the same frame. Pacific Scientific offers the unit as a Standard Motor, so it comes without special windings or custom sealing options. It is identified as a PMB Series Brushless Servomotor for drive matching within the series. This combination of frame size, encoder arrangement, and shaft style makes the motor suitable for controlled motion duties that require stable feedback and dependable torque transfer.
