Product Description:

The 8JSA32.E4055D000-0 is a synchronous motor manufactured by B&R Automation for the 8JS Synchronous Motors series. The design supplies direct torque to servomechanisms in packaging lines, pick-and-place stations, and other automated equipment that depend on consistent speed and position control. In these roles, the motor converts drive current into accurately timed rotation for machinery requiring compact dimensions and fast feedback. Its synchronous operation allows a compatible servo drive to regulate shaft movement according to commanded speed, torque, and position profiles.

The rotor reaches a nominal speed of 5500 rpm, giving motion controllers a wide operating range for high-throughput cycles. Position feedback is delivered by an optical encoder with a resolution rating of 13/0 bits S/M, providing detailed position data for controlled motion. Encoder accuracy remains within ±60 arcseconds, supporting precise position measurement throughout the operating range. The encoder communicates through the optical EnDat 2.1 protocol, allowing the drive to receive digital feedback for closed-loop control. Thermal management relies on self-cooling, eliminating the need for an external blower and reducing the amount of auxiliary equipment around the motor. The stator uses motor size 3 and length 2 to balance torque capacity with the available installation space.

The housing supports flange mounting, allowing the motor face to bolt directly to a gearhead or machine frame while maintaining alignment. Power and signal leads exit through an angled swivel connector, which makes cable routing easier in confined enclosures and reduces sharp bends near the housing. Output torque is transferred through a smooth shaft, so a suitable clamping coupling can connect the motor to the driven equipment. The feedback device is a single-turn encoder, providing an absolute position within one mechanical revolution without a battery-backed multi-turn counter. The motor is supplied without a holding brake, so an external mechanism or drive-applied torque must retain stationary loads when required. It also has no oil seal, which reduces seal friction but requires the installation area to protect the shaft interface from oil and other contaminants.
