78W Integrated Servo Motor in a 42 mm Frame

78W Integrated Servo Motor in a 42 mm Frame

The iHSV42-40-07-24 is a 78W Integrated Servo Motor on a 42 mm (NEMA17-class) frame, rated at 78 W and 5.1 A with a rated speed of 4000 RPM and an 83 mm body length. The higher speed rating suits applications where compact size matters more than peak torque, and the integrated drive keeps the whole axis within the small frame.

closed loop Control in a Small Package

Digital position, speed, and current loops are closed with incremental encoder feedback. Locating the amplifier on the motor avoids the long shielded wiring that small machines often have trouble routing, and keeps the wiring short and reliable.

Duty and Thermal Expectations

Continuous current is 5.1 A. Small frames dissipate heat through a limited surface, so the unit is best suited to intermittent or moderate-duty motion where the duty cycle keeps average current below rated. The low-vibration characteristic helps with precision at 4000 RPM.

Key Specifications

• Frame size: 42 mm
• Body length: 83 mm
• Rated power: 78 W
• Rated current: 5.1 A
• Rated speed: 4000 RPM
• Encoder: incremental
• Integration: drive and motor in one unit

Design and Integration Notes

The 4000 RPM rating gives machine designers a wider speed window for applications that need fast positioning moves without oversized motors. The integrated amplifier eliminates the need to select and tune a matching drive, which is a common source of engineering time in small servo projects.

Applications

The 42 mm unit is practical for industrial automation, robotics, packaging machinery, and CNC machine tool axes where compactness is the priority. It is also suited to small medical and laboratory equipment that requires a clean, integrated motion axis with low noise.

Selection Considerations

Check that the supply can deliver the 5.1 A current and that the 83 mm body length fits the layout. Because the frame is small, keep duty cycle in mind for continuous runs. Our team can help confirm the torque-speed profile for your application and supply the matching connector.
