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.

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. 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

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