Product Description:
The PMA22B-00100-00 brushless servomotor is produced by Pacific Scientific within the PMA Brushless Motors series. It is intended for precise speed and position control on automated axes used in packaging, material handling, and general-purpose machinery. By combining permanent-magnet excitation with electronic commutation, the motor supplies regulated torque without brushes. That arrangement supports repeatable motion on axes that start, stop, and reverse frequently. Integrated rotor position feedback supports closed-loop operation with compatible drive amplifiers.
At its thermal limit, the motor sustains 1.3 Nm of continuous stall torque. During rapid indexing, it can reach 4.7 Nm of peak torque for brief intervals. These outputs require a winding stall current of 2.7 ARMS, so the companion drive must supply that current at standstill. With a rotor inertia of 0.038×10⁻³ kg·m², the rotor spins up quickly, which helps reduce settling time in tight position loops. The copper windings are rated for 240 V AC max, allowing use with compatible PWM inverters. The motor uses stack length code 2, which keeps the housing compact.
The frame has a 70 mm square cross-section that fits compact machinery layouts. The unit weighs 2.3 kg, which helps limit moving mass on smaller gantries. Power conductors terminate on a 6PP right-angle connector, so cabling can exit parallel to the mounting surface. This connector orientation can be useful when rear cable clearance is limited. Feedback wiring leaves from the same side, which can reduce bundle stress and help in tight installations. Position information is supplied by a resolver, providing noise-immune analog signals to the drive. The smooth shaft simplifies coupling to low-backlash clamps, and because the motor is supplied without a brake, any holding torque must be provided by the drive or external mechanics. The motor uses a standard design without special feature options.
