Product Description:

The PMB11B-10Y14-04 is a permanent-magnet brushless servomotor manufactured by Pacific Scientific for the PMB Brushless Servomotors series. It converts electrical power from a matched drive into tightly regulated shaft rotation for compact pick-and-place units, laboratory dispensers, and light packaging equipment. The motor is suited to applications that need repeatable positioning in a limited installation space. It can also be used on indexing devices, feeders, and compact handling modules where available mounting space is restricted. Its compact format fits short-travel axes and small rotary assemblies that must accelerate, settle quickly, and repeat the same motion path over long production runs.

This motor uses a Size 17 frame, giving it a compact square faceplate for small automation stages and light mechanical loads. Motion feedback is supplied at 2048 ppr by an integrated Digital Encoder with commutation, so the drive can monitor position and speed while maintaining electrical phase alignment without separate Hall devices. Continuous stall operation is supported when the amplifier can deliver 2.7 ARMS, which allows the motor to hold load at zero speed without excessive heating in normal servo use. The output uses a round shaft, so torque is transferred through a clamping hub, collet, or similar coupling that grips the full shaft surface.

A stack length multiple of 1 means the motor uses a single lamination stack, which helps keep rotor inertia low for quick acceleration and deceleration. The brushless construction removes mechanical commutators, reducing wear during extended duty cycles. Electronic commutation works with the encoder signals to keep rotation smooth across the operating range, especially during frequent starts and stops. This arrangement is well suited to light-duty servo axes where stable low-speed control and responsive motion are both important.
