Product Description

PMB31B-10100-01 is a top-rated brushless servomotor manufactured by Pacific Scientific. The company has proven expertise in the field of motors with different types of motors to suit just about any requirement. The B series motor has a frame size of NEMA size 34 and multiple stack length. The unit has a B style winding designator with a nominal stall current of 2.7A.

The motor encompasses an IP40 construction style and a round shaft. It features a maximum operating voltage of 320VDC or 240VAC. The unit supports AMP mini Mate-N-Lock type electrical connectivity option on 18” lead connectors and a resolver type of sensor. The device can be customized to accommodate a shaft seal. The black rectangular synchronous servomotor houses eight poles and neodymium-iron-boron magnets. The choice of material for the magnets results in producing maximum torque to enhance the efficiency of the motor. The double shield ensures the long life of the bearings while the exposed-lam design offers assurance of maximum torque and power. The motor has a Class F winding insulation and a current rating of 8A at peak torque.

The servomotor has an overall size of 5.28 inches and low inertia of 0.137kgm² x 10^-3 with the resolver sensor. The ideal operating temperature for the unit is 25°C. The device has maximum static friction of 0.09Nm, typical rated torque of 1.90Nm, a line-to-line resistance of 7.6 ohms and a line-to-line inductance of 19.6mH. The motor operates at a rated speed of 2,900RPM. The cost-effective black colored brushless motor renders improved application flexibility. This ensures that the unit is ideal for use in light industrial and high volume applications related to position and speed control that need both high torque and acceleration. The lightweight motor weighs only 2.5kg and this makes the unit easily portable.
