24 VDC closed loop Stepper Motor with Integrated Driver

The iESSH42-24-05-17BC-RC/EC is a 24 VDC closed loop Stepper Motor rated at 0.5 N·m holding torque with a 1.5 A phase current, integrated into a 42 mm frame together with its drive. It is a low-power choice for axes that prioritize a small envelope over raw torque, and it is supplied as a self-contained module for light-duty positioning and robotic mechanisms.

Matching Torque to the Load

Half a newton-metre covers light grippers, small turntables, and low-inertia transfer devices. Because the drive and motor share one body, the axis can be pre-assembled as a module and dropped into the machine frame.

Control and Communication

closed loop control maintains position under varying friction, and the 17-bit absolute encoder reports position immediately at power-up. The 17-bit resolution provides enough position detail for small precision stages where smooth, repeatable motion is required. RS485+CAN and EtherCAT variants are available for connection to the machine controller.

Specifications

• Frame size: 42 mm
• Holding torque: 0.5 N·m
• Supply voltage: 24 VDC
• Rated current: 1.5 A
• Fieldbus: RS485 + CAN / EtherCAT
• Encoder: 17-bit absolute
• Control: closed loop

Heat and Cycle Rate

With only 1.5 A through the windings, copper loss stays modest, which helps in compact enclosures. Continuous duty still requires the frame to radiate heat; intermittent operation at rated torque is the intended envelope.

Applications

• Industrial automation
• Packaging machinery
• Robotics
• CNC machine tools

Selection Considerations

This unit is best selected when the mechanism operates intermittently and the duty cycle stays well below continuous operation. Compare the 0.5 N·m rating against the worst-case load including acceleration torque, and confirm that the 24 VDC supply can hold the 1.5 A peak current at the drive input. For light-duty applications, the integrated drive reduces the number of parts to stock and shortens installation time on the production line.
