Product Description:

The PMB33E-00101-01 is a brushless servomotor built by Pacific Scientific for the PMB Brushless Servomotors series. In automated machinery, it translates drive commands into precise shaft rotation, letting motion controllers position loads quickly and repeatably across packaging lines, pick-and-place modules, or indexing tables. It remains compatible with a wide range of Pacific Scientific controllers, allowing the motor to be paired with factory-supplied velocity or torque loops without additional tuning.

The frame follows the NEMA Size 34 standard, so the mounting face measures 3.4 inches square and fits common gearheads and brackets without adapter plates. During locked-rotor testing at 240 VAC, the motor draws a nominal stall current of 7.4 ARMS; this figure helps with drive sizing for maximum continuous torque production while preventing thermal overload. Rotor position feedback comes from an integral Hall sensor, enabling six-step electronic commutation without an external encoder. Internally, the stack length multiple is 3, so three lamination sections are used to raise flux density and increase torque compared with shorter stacks in the same frame. Power and signal conductors exit the housing as flying leads with AMP connectors, giving the user the option to terminate leads directly inside a cabinet or mate them to prewired harnesses for easier connection.

The output shaft is machined with a flat, so set-screw couplings grip reliably under reversing loads while still allowing easy axial removal. A configurable shaft seal can be specified to block oil mist or fine dust from entering the front bearing when the motor is mounted in washdown or machining cells. It is a PMB Series Brushless Servomotor, so the winding insulation, bearing selection, and thermal rise limits follow the series guidelines for continuous industrial duty.
