Product type
A servo motor drive is an electronic device that controls the motion of a servo motor by regulating its position, speed, and torque. These drives are typically composed of a power supply, control circuitry, and feedback systems that allow for precise control of the motor's movements. They are essential components in automation systems, enabling machines to perform tasks with high accuracy and repeatability.
| Input voltage range | 24V to 480V |
| Control type | Pulse Width Modulation (PWM) or analog |
| Communication protocols | EtherCAT, CANopen, Modbus |
| Output current | Up to 100A or more, depending on the model |
| Feedback type | Incremental or absolute encoders |
| Operating temperature range | -10°C to 60°C |
When selecting a servo motor drive, consider the specifications of the servo motor it will control, including voltage, current, and feedback type. It's important to specify the required communication protocols for integration with existing systems. Buyers should also evaluate the operating environment and ensure the drive can function within the temperature range needed for their application. Additionally, consider the quantity needed for your project to ensure bulk pricing if applicable.

Servo motors provide continuous rotation and precise control, while stepper motors move in discrete steps.
No, servo motor drives are specifically designed for servo motors and may not work with other types.
Common feedback devices include incremental encoders, absolute encoders, and resolvers.
The size should match the motor's voltage and current ratings, as well as the application requirements.
Yes, many servo motor drives offer programming options for custom control and operation.
Look for features like overcurrent protection, thermal protection, and safe torque off capabilities.
