Product Description:

The PMA22B-01100-00 is a brushless servomotor produced by Pacific Scientific within the PMA Brushless Motors series. In automated machinery, it converts drive current into precise rotary motion so positioning controls can regulate speed and torque without mechanical commutation. Because commutation is electronic, the motor avoids brush wear and supports consistent response over repeated duty cycles. This type of motor is suited to tightly coordinated axes in packaging equipment, pick-and-place stages, and similar systems where stable feedback and repeatable motion are required during frequent start-stop cycles.

A continuous stall torque of 1.3 Nm allows the shaft to hold static loads without overheating during sustained operation. The motor can also deliver a peak torque of 4.7 Nm for short acceleration events or brief load changes, while its 70 mm square body supports installation in compact servo assemblies. Rotor inertia is 0.038 kg·m² × 10⁻³, which supports quick speed changes with limited overshoot when the axis is tuned correctly. To produce rated torque at stall, the windings require 2.7 A RMS of continuous phase current. The motor uses stack length 2, which increases copper volume compared with a shorter stack and adds thermal mass without increasing the mounting footprint.

An integrated 24 V brake holds the axis when power is removed, which is useful on vertical or suspended loads that must remain in place at standstill. Power is routed through a right-angle 6PP 6-pin connector, while position feedback is provided by a resolver and the smooth shaft supports clamped couplings without a keyed interface. The insulation system permits a maximum winding voltage of 240 V AC, matching many common servo amplifier output levels. The motor weighs 2.3 kg, which helps keep moving assemblies compact and reduces added load on mobile machine members.
