Product Description:
A brushless servomotor of the PMB series, the Pacific Scientific PMB33F-20116-00 is utilized for precise movement control and provides a high torque density.
Since the motor is constructed in a NEMA 34 frame size with a stack multiple of 3, it is both compact and sturdy. It has flying leads in AMP connections, which include a rapid, secure, and effective electrical connection to automation systems, for dependable industrial operations. Position feedback and smooth, regulated movement are ensured by this model's digital commutating encoder, which offers a precision of 4096 pulses per revolution. When considering a combination of torque value and efficiency, the motor's winding designator is F. The greatest torque that the motor can produce is 12.5 Nm (111 lb-in), with a consistent stall torque of 5.4 Nm (48.0 lb-in). Having a steady 4.1 kW protected power output, it can be used in medium- to high-performance servo applications.
The PMB33F-20116-00 is rated with a nominal stall current of 11.0 ARMS to provide stability of its operation when under load. It also offers a peak current capacity of 21.2 ARMS, thus permitting it to accommodate abrupt acceleration and transient-type loads. A reasonable compromise between quick response and steady operation is provided by the motor rotor inertia, which is 0.40 kg · cm² (3.57 lb·in·s²). The motor is mechanically light (its weight is 2.8 kg only) and still has to endure the required amount of friction due to ongoing industrial use. It is constructed on the basis of 3-phase, 8-pole construction, which permits comfortable production of torque and effective work performance in the entire operating range.
