Product Description:

The PMA23B-10100-00 is a brushless servomotor built by Pacific Scientific for the PMA Brushless Motors series. With brushless electronic commutation and a permanent-magnet rotor, the motor provides precise position and velocity control for automated pick-and-place axes, small gantries, and indexing tables on the factory floor. It translates drive current from a digital amplifier into repeatable rotary motion while maintaining tight synchronization with controller feedback loops. This operating principle supports controlled acceleration, deceleration, and positioning during repetitive machine cycles.

Its stack length code of 3 indicates a lamination depth that supports a continuous stall torque of 2.0 Nm, while short bursts can reach a peak torque of 7.2 Nm for rapid acceleration. A square housing measuring 70 mm on each side simplifies mounting to compact gearboxes or direct-drive loads. Rotor inertia is kept to 0.055 × 10⁻³ kg·m², which helps the servo loop achieve a fast dynamic response without excessive overshoot. The windings draw 2.7 A RMS at nominal stall, and the supply cable terminates in a 6-pin power connector that keeps power connections separate from signal lines. A resolver mounted on the rear end provides rotor-angle information to the drive for closed-loop control. The shaft has a closed keyway with the key fitted, allowing it to transmit torque to a coupling without slipping. The motor is supplied without a brake, so an external holding device may be required when a stationary load must remain secured after motor power is removed.

For cabinet layout, the mating power plug uses a right-angle orientation, allowing the cable to exit sideways and clear adjacent axes. The windings accept supplies up to a maximum of 240 V AC, making the motor compatible with common mid-power digital amplifiers without step-down converters. The motor weighs 2.9 kg, which reduces the static load when it is installed on a moving machine member. Its compact housing and sideways cable exit also help preserve clearance around nearby equipment without changing the required mounting arrangement.
