Product Description:

The PMA42Q-10100-00 is a brushless servo motor produced by Pacific Scientific within the PMA Brushless Motors series. It converts commanded current from a drive into rotational motion that positions loads with repeatable accuracy, making it suitable for indexing tables, packaging machines, and coordinated multi-axis cells in industrial automation. Because it is a synchronous permanent-magnet unit, it maintains speed regulation over a wide torque range.

This model supplies a continuous stall torque of 4.1 Nm, indicating the sustained load it can hold without overheating, while its peak torque ceiling of 14.6 Nm supports rapid acceleration during short duty bursts. A rotor inertia of 0.36 ×10⁻³ kg·m² balances quick response with mechanical damping, limiting overshoot during direction reversals. The winding requires only 7.4 ARMS of stall current, so standard mid-range drives can energize the motor without oversized power electronics. Rated for 240-480 V AC, the winding accommodates common three-phase plant voltages and allows long cable runs with reduced current drop. Cabling exits through a right-angle 6-pin 6PP power connector, which simplifies routing in shallow enclosures. No integral brake is fitted, so holding torque must be provided by the drive or an external mechanism when power is removed.

The square housing measures 115 mm on each side, a profile that fits ISO-standard motor mountings, and stack length code 2 gives moderate axial depth for compact machines. The motor has a mass of 6.2 kg, which is light enough for mounting on moving carriages while still helping damp vibration. A shaft with a closed keyway and fitted key transmits torque to pulleys or couplings without slip. Position feedback comes from a Resolver, providing rotor angle and speed data to the drive in high-temperature or electrically noisy environments.
