Product Description:
The PMA22B-01100-22 brushless servomotor is produced by Pacific Scientific as part of the PMA Brushless Motors series. Designed for closed-loop positioning and speed control, it supports precise motion on assembly lines, pick-and-place gantries, and electronic packaging stations. A rotor-mounted resolver returns shaft-angle feedback so the drive can regulate current and follow the commanded motion profile. Its compact square housing simplifies installation when multiple axes must fit into a limited enclosure. This arrangement supports repeatable starts, stops, and reversals in tightly spaced machine layouts.
During continuous operation at zero speed, the motor delivers 1.3 Nm of stall torque, giving vertical actuators enough holding capacity for static loads. For rapid indexing moves, it withstands up to 4.7 Nm of peak torque, providing acceleration headroom before thermal limits are reached. Velocity loop response is influenced by a rotor inertia of 0.038 kgm² × 10-3, allowing tight tuning without overshoot on light mechanical stages. The windings draw a nominal stall current of 2.7 A RMS, which helps match the motor to a suitable amplifier and cable set. Coil insulation is rated for 240 V AC maximum, so the electrical system can operate safely on compatible 240 V servo drives. This combination suits axes that need steady holding torque at standstill and short bursts of higher acceleration.
The square frame dimension is 70 mm, so units can mount side by side on narrow plates. A right-angle 6PP six-pin power connector lets the cable exit parallel to the motor body, reducing bend stress where rear clearance is limited. An integral 24 V brake clamps the shaft when power is removed, helping prevent unwanted axis movement. Even with the brake installed, overall mass remains 2.3 kg, and the two-layer stack length keeps the motor short. The smooth shaft eases alignment with precision couplings and supports low-backlash drive connections.
