750W 48V Servo Motor – 2.38 N·m with Holding Brake

The 80ASM750-5-17BCH is a 750W 48V Servo Motor that produces 750 W of continuous output on a 48 VDC bus within an 80 mm frame. Continuous torque is 2.38 N·m at a rated 3,000 r/min, and the 17-bit magnetic encoder and built-in electromagnetic brake make it a good fit for feed rollers, transfer axes and turntables in automated handling systems.

Rated for continuous 750 W output

This specification suits moderate-inertia axes in packaging, factory automation and material handling without over-provisioning the drive. Running from 48 VDC keeps the control cabinet simple and reduces the insulation stress that a 380 VAC bus would impose.

Absolute feedback keeps position on restart

Its 17-bit magnetic encoder removes the need for homing after a power cycle, reducing cycle time on intermittent-duty machines. The driver uses this feedback for closed loop commutation, so position error is measured directly rather than estimated.

Brake and temperature management

A built-in electromagnetic brake holds the load when de-energized, important on indexing and vertical-travel axes. At continuous rated torque the winding temperature stays within the datasheet rise; the low-voltage design avoids the higher insulation stress of 380 VAC bus motors.

Application scenarios

Used in CNC machine tools, packaging, robotics, factory automation, textile, printing, food processing, material handling, battery manufacturing and AGV/AMR. The 80 mm frame and 48 VDC compatibility keep onboard electronics simple on AGV/AMR platforms, while packaging lines rely on the 2.38 N·m torque for servo-driven conveyors and rotary indexing stations.

Selection and operating notes

Match the driver current and bus voltage to the 48 VDC rating and confirm the brake release signal is wired correctly before powering vertical axes. At 750 W the motor suits moderate-inertia loads; for heavier duty, step up to the 1,000 W 80 mm variant instead of overloading the drive. Ensure the frame is mounted to a heat-conducting surface for continuous 3,000 r/min operation, and verify the torque required at your working speed against the torque-speed curve.
