Product Description:
The PMA22B-10114-01 is a brushless servomotor built by Pacific Scientific for the PMA Brushless Motors series. This low-inertia motor supplies closed-loop rotary motion to positioning tables, pick-and-place heads, and other automated axes that require repeatable speed and torque under drive control. Within those systems, the motor converts regulated electrical power from a matched amplifier into mechanical shaft rotation for precise industrial automation tasks.
At continuous stall, the motor can deliver 1.3 Nm, while its magnetic circuit supports a peak output of 4.7 Nm for short acceleration bursts. A rotor inertia of 0.038 × 10⁻³ kg·m² keeps load matching favorable so the drive can achieve fast response without overshoot. Winding design limits steady stator current to 2.7 ARMS, and the copper insulation is rated for supplies up to 240 V AC maximum. Feedback is provided by a digital encoder with commutation tracks at 2048 pulses per revolution, giving the controller both position information and phase reference signals. The shaft has a closed keyway with the key fitted, and the motor has no brake, so any holding function must come from the drive or external mechanical hardware. The motor uses two lamination stacks with length code 2, which correspond to the active magnetic core and overall housing depth.
Cable access is through a right-angle mating end, and power enters on a 6PP (6-pin power) connector, allowing strain-relieved routing inside compact cabinets. The square frame measures 70 mm on each side, making it compatible with ISO flange adapters and inline gearboxes of the same pitch circle. Total mass is only 2.3 kg, reducing load on linear guides and making handling easier during installation. An oil seal is fitted at the front bearing to limit lubricant loss and help keep contaminants out of the stator cavity. This arrangement supports reliable service in moderate splash zones.
