Product Description:
The PMA13B-10100-00 is a brushless servomotor produced by Pacific Scientific and assigned to the PMA Brushless Motors series. Intended for precision motion axes, the unit converts three-phase drive outputs into controlled torque without the wear associated with a mechanical commutator. The motor is delivered without a brake, so an external holding device or drive-generated torque is required when a stationary load must be secured. Its stack length of 3 places the magnetic core in the middle of the available frame range, balancing torque density with the motor’s overall footprint.
The motor has a rated stall torque of 0.9 Nm, providing holding force for gearless couplings in light pick-and-place stations and similar automated equipment. The windings draw 2.7 A RMS to produce this torque, so the selected drive amplifier must provide the required continuous current while maintaining acceptable winding temperatures. The insulation system supports up to 240 V AC on the phase leads, making the motor suitable for compatible servo drive systems. A square body width of 55 mm provides a compact installation envelope while offering sufficient surface area for heat dissipation. Power reaches the stator through a 6-pin power connector. Its right-angle housing allows the cable to run parallel to the mounting surface, reducing the clearance required behind the motor and simplifying routing in shallow machinery.
The motor provides a peak torque of 4.3 Nm, allowing short acceleration bursts without saturating the magnetic circuit. Rotor inertia is 0.026 kg·m² × 10⁻³, helping the axis accelerate quickly and settle promptly after rapid position changes. The motor has a mass of 1.9 kg, allowing it to be mounted on moderate-sized linear stages without placing excessive load on the supporting structure. Position data is supplied by a resolver, which reports rotor angle throughout the operating speed range for closed-loop position and velocity control. Torque is transmitted through a shaft with a closed keyway and fitted key, providing positive engagement with pulleys, gearboxes, or rigid couplings.
