Product Description:
The PMB31D-00100-01 is a brushless servomotor manufactured by Pacific Scientific and supplied within the PMB Brushless Servomotors series. It is designed to convert commanded current into precise rotary motion for tightly controlled axes in automated assembly, packaging, and semiconductor tools where repeatable positioning is required throughout long duty cycles. When paired with a compatible drive, the motor delivers closed-loop torque for accurate load positioning and repeatable motion during indexing, transfer, and handling tasks.
The frame follows the NEMA Size 34 standard, so its mounting face lines up with common 3.4-inch square motor brackets used in compact machinery and other space-limited motion assemblies. At locked rotor and 240 VAC, the winding can carry a nominal stall current of 5.4 ARMS, which indicates how much continuous torque the drive can request before thermal limits are reached. Power and feedback leave the housing through flying leads with AMP connectors, and these pre-terminated pigtails simplify cable routing while reducing termination work during installation. Rotor position is detected by a resolver, giving sine and cosine feedback that tolerates heat, shock, and electrical noise better than many optical encoder arrangements in demanding industrial environments. The output shaft has a flat along one side, making it easy to clamp pulleys or couplings without relying on keyways and reducing the number of parts in the drivetrain.
Mechanical length is set by a stack length multiple of 1, which is the shortest lamination stack offered in this motor family and helps keep inertia low for rapid acceleration and responsive direction changes. A factory-installed shaft seal helps block oil or dust from reaching the front bearing when the motor is mounted in washdown equipment. The motor is part of the PMB Brushless Servomotors series, which uses a common mounting format across different torque ratings in the family and supports consistent fit within the same machine envelope.
