Product Description:

The PMA22B-10100-00 is a brushless servo motor produced by Pacific Scientific in the PMA Brushless Motors series. It is intended for positioning and velocity control in automated packaging systems, material handling equipment, and light machine tool axes where compact size and stable motion are important. The motor converts drive current into rotary motion and uses an integrated feedback device so the drive can maintain closed-loop control during speed and position changes. Its brushless design reduces routine maintenance, and its compact form helps it fit matched drive and gearhead combinations without taking up excessive installation space.

The motor has a continuous stall torque of 1.3 Nm, which indicates the steady load it can hold without overheating under proper operating conditions. Its peak torque reaches 4.7 Nm for short acceleration demands, giving the axis extra output during brief load changes. At stall, the winding draws up to 2.7 ARMS, and the rotor inertia is only 0.038 × 10⁻³ kg·m², which supports quick response to changing speed commands. The housing uses a 70 mm mounting face, and the motor has stack length 2 with a closed keyway shaft for secure torque transfer into the driven mechanism.

The winding is rated for supply voltages up to 240 V AC max, making it suitable for common industrial drive systems. The motor has a total mass of 2.3 kg, which helps limit added load on smaller moving axes and compact linear stages. Power is connected through a 6PP (6-Pin Power) connector mounted at a right angle to the housing, which helps with cable routing where depth is limited. Feedback is provided by a resolver that returns rotor position information across the speed range, and the motor is supplied without a brake so rotating inertia stays low and back-drive behavior remains predictable during stopping.
