Product Description:
The PMA22V-00100-01 brushless servomotor is produced by Pacific Scientific and belongs to the PMA Brushless Motors series. It is intended for closed-loop positioning and velocity control in CNC axes, pick-and-place heads, and other automation stations where compact torque density is needed. By combining rare-earth magnets with electronic commutation, the unit delivers repeatable motion without brush maintenance, allowing machine builders to integrate a durable rotary actuator directly into machinery.
The motor’s continuous stall torque is rated at 1.3 Nm, indicating the load it can hold indefinitely without exceeding thermal limits, while a peak capability of 4.7 Nm supports short acceleration bursts. Its square frame measures 70 mm, permitting installation in compact servo packages commonly used on small gantries and indexers. Dynamic response is aided by a rotor inertia of 0.038 kg·m² × 10⁻³, so control loops can achieve rapid speed changes with limited overshoot. The housing has a mass of 2.3 kg, making it suitable for moving-axis installations while providing enough mass to dissipate winding heat during demanding duty cycles. The motor has no internal brake, which reduces its length and eliminates residual drag while allowing the shaft to rotate freely when power is removed.
A 6PP 6-pin power connector carries phase current, and its contacts exit through a right-angle header that keeps cable bends within shallow cabinets. Feedback to the drive originates from a resolver, which provides analog sine-cosine signals for rotor position feedback at power-up and during operation. Stack length code 2 adds magnetic depth to the base frame, increasing torque without widening the motor body. A smooth shaft simplifies attachment to collets or timing pulleys without requiring a keyed connection. An integrated oil seal helps retain lubricant when the motor is flange-mounted against a gearbox or linear actuator.
