Product Description:

This PMB33E-20114-03 brushless servomotor delivered by Pacific Scientific renders cost-effective high performance. The motor’s permanent magnets help in achieving high torque-to-inertia ratio. This product is put to use with a brushless servo drive of the PC800 series. The device portrays an exposed design. This unit comprises Class F winding insulation. It is categorized as a PMB series motor. The motor is best suited for closed-loop control applications.

This product features an IP 40 construction. The device has a NEMA 34 frame size. This unit’s mating connectors are to be obtained separately. It houses a shaft seal as well as a PTC thermistor. The motor’s encoder comes with commutation capability. This product’s frame incorporates four equally spaced mounting holes. The device needs 10 fillister-lead or socket-lead cap screws for its mounting. This unit’s bearings are made of a combination of neodymium, iron, and boron. It has an operating voltage of 240 VAC and a bus voltage of 320 VDC.

The motor delivers synchronous operation. This product is highlighted by a compact construction and is one of the best choices for light industrial applications. The device uses 18-inch flying leads for connection. This unit depicts low maintenance because of the absence of brushes. Its shaft is fitted onto the rotor. The brushless servomotor’s magnets are organized in pole pairs. This product’s stator generates electromagnetic fields when it is in its operational phase. The device is deployed in multiple industrial sectors. This unit comprises assimilated end bells in the front and rear. Its feedback system interacts with the supporting servo drive to provide information about velocity and position.
