Product Description:

The Pacific Scientific PMB33F-20216-02 is a brushless servomotor that belongs to the PMB series and is utilized in severe automation systems.

The IP protection rating of this motor offers a compact casing that supports steady torque and speed operation, all built to match NEMA 34. For communication and simple integration into any kind of machine system, the flying leads come with MS connectors. The motor has a digital encoder that is commutated, which gives the encoder resolution of 4096 pulses/revolution and, thus, discrete position and velocity feedback. High resolution is provided, which provides smooth operation and proper control, making the motor suitable for high-performance servos. With a stack length that is a multiple of three, the design maximizes torque density while maintaining a reasonable form factor. The PMB33F-20216-02 is appropriate for applications requiring prolonged loads since it can provide 5.4 Nm of continuous peak torque and 4.1 Nm of continuous nominal torque.

The highest stall torque of 12.5 Nm can be obtained using the motor in dynamic or peak demands. Due to its maximum speed rating of 5700 rpm and its no-load working speed of 4500 rpm, it may be employed to offer both high-speed operation and torque. The stall current at 240 VAC is nominally 11.0 ARMS, which supports the high torque properties of this device. Mechanical specifications also have a total length of 210.3 mm, a 98.43 mm diameter of the mounting bolt circle, and four mounting holes with a diameter of 5.59 mm. The pilot diameter is 73.08 mm, which allows standard mounting and also provides stable alignment. It can be purchased at Wake Industrial with a one-year warranty.
