Product Description:

The PMB33F-10116-02 is a brushless servomotor produced by Pacific Scientific and included in the PMB Brushless Servomotors series. As a rotary actuator, it is used on industrial automation axes where repeatable speed and position are required, such as indexing tables, transfer units, and pick-and-place heads. The motor works with a servo amplifier that regulates current from feedback signals, allowing the machine to follow programmed motion profiles with low settling time and stable response during repeated cycles.

The motor frame conforms to NEMA Size 34, so the mounting holes and pilot fit match standard 3.4-inch square flanges used on medium-torque stations. During startup or locked-rotor conditions, the winding can draw up to 11.0 ARMS of nominal stall current at 240 VAC. This value is used to match the motor with a suitable servo amplifier and protective devices. Rotor position feedback is delivered through an integral encoder that supplies 4096 ppr of resolution, giving the controller fine position data for commutation and velocity control. The feedback device is a Digital Encoder with commutation, so separate Hall sensors are not required. Power and feedback signals exit through Flying leads with AMP connectors, which support direct connection to matching cable harnesses.

Thermal protection is built in through a PTC Thermistor, allowing the drive to monitor winding temperature and limit current if the motor begins to overheat. The output shaft has a Round profile, allowing direct coupling with clamp hubs or custom gears where a keyed shaft is not required. Magnetic length is established by a 3-stack lamination, which increases torque density without exceeding the frame envelope. The unit is classified by Pacific Scientific as a PMB Series Brushless Servomotor. This motor format supports precise motion control in compact installations where consistent encoder feedback and integrated thermal monitoring are important.
