Product Description:
The PMB31B-10101-01 is a Servo motor designed by Pacific Scientific for use in industrial automation systems. The connection type includes flying leads with amp connectors for secure installation and integration. The motor is part of a durable and cost-effective range, with a NEMA Size 34 frame.
The servo motor's winding is rated at 2.7 A, and its inductance (L) is 19.6 mH. The servo motor has a Hall sensor as its principal feedback element. The PMB31B-10101-01 servo motor has a continuous stall torque of 2.1 Nm and an ICS of 2.7 ARMS. The rated speed is 2,700 revolutions per minute, whereas the speed when there is no load is 4,300. For the purpose of motor connection, the PMB31B-10101-01 utilizes shielded 18 AWG wires and features a round shaft. A cable with a shielded 26 AWG gauge is used for the feedback connection. The inertia is 0.14 ×10⁻³ kgm², which allows for consistent motion control. The stack length is 134.1 mm, which makes it suitable for installations with limited depth. The continuous rated torque is 1.9 Nm, which equates to 16.9 lbs-in. The frame size is NEMA 34, which corresponds to conventional mechanical interfaces.
The PMB31B-10101-01 servo motor has a shaft suited for rotational applications and feedback via shielded cables. Accurate location tracking is made possible by the sensor, which is a technique based on Hall. Integration with servo drives is made easier by these qualities, which, when combined with standardized mounting dimensions and cable gauges, make the process more feasible. The top-rated torque is 4.7 Nm, which translates into a peak current of 6.0 ARMS. The servo motor is designed to perform at rated torque levels and is supported by consistent winding parameters.
