Product Description:
Sanyo Denki manufactures the Super DC Servo Motor under product code V720-032EL8. This model is designed for precise motion control in industrial systems. The motor features a compact outer diameter of 76 mm. It delivers a rated output of 20W for stable performance. The voltage specification is fixed at 75V for consistent input supply.
The V720-032EL8 Super DC Servo Motor has a rated armature voltage that is maintained at 80V. This ensures smooth torque generation during operation cycles. The motor includes a line driver encoder with 1000 P/R resolution. This provides accurate position feedback and enhances control precision. The rated torque is 0.64 Nm under continuous operation. The motor operates at a rated speed of 3000 rpm. It supports a maximum rotating speed of 5000 rpm. The continuous stall torque is rated at 0.77 Nm and friction torque is limited to 0.04 Nm for reduced drag. These values allow efficient performance with minimal losses. The torque ripple is measured at 3.5 % for smooth rotation. The torque constant is defined at 0.23 Nm/A. This enables effective torque response per ampere input. The power rate is optimized at 2.7 kW/s for quick acceleration. The motor has an armature winding resistance that is set at 2.8 ohms. This provides thermal stability during long operation.
The V720-032EL8 Super DC Servo Motor has a mass of 1.8 Kg for compact mounting and transport. The motor supports systems needing high-speed motion with control accuracy. The Super DC Servo Motors line offers reliable operation in demanding conditions. The product code V720-032EL8 reflects its engineering category and integrates precision feedback with balanced torque and speed specs. It is built for use in automated machinery and servo applications.
Frequently Asked Questions about V720-032EL8:
