Product Description:

The PMB33C-10214-00 is a brushless servo motor produced by Pacific Scientific within the PMB Brushless Servomotors series. It converts electric power into precise rotational motion for closed-loop positioning tasks in industrial automation, such as indexing tables or gantry axes. By supplying smooth torque and rapid response, it allows machine controllers to regulate velocity, position, and acceleration directly at the motor shaft. This operating behavior suits applications that need repeatable starts, stops, and controlled changes in speed. In servo systems, that controlled motion helps maintain accurate path following during indexing, transfer, and positioning cycles where repeatability matters.

The motor uses a NEMA Size 34 frame, making it physically compatible with common 3.4-inch square mounting patterns in packaging machines and small presses. With a maximum supply of 240 VAC, it draws a nominal stall current of 3.8 ARMS when the rotor is locked and high torque is required. Position feedback comes from a digital encoder with an output of 2048 ppr, allowing the controller to resolve 2048 discrete positions per shaft revolution for accurate servo loops. Power and feedback conductors exit as flying leads with MS connectors, which allows standard plug-in connections at the wiring harness. The motor has a round shaft for coupling to gears or belt pulleys without keyways.

The feedback system is a digital encoder with commutation, so one device provides incremental position data and the signals needed for electronic switching. The rotor uses a stack length multiple of 3, which gives the motor more active length than shorter units in the same frame and supports higher torque output. Using one feedback device for both position sensing and commutation keeps the motor package compact and avoids a separate commutation sensor assembly. It is supplied as a standard motor with no factory customization, making it suitable for general-purpose servo installations.
