Which is the better choice for valve actuators: stepper motor or synchronous motor?

Both stepper motors and synchronous motors can be used as actuators for valve control applications, depending on the different specific requirements of the application.

Stepper motors are often used in valve actuator applications that require precise control of the valve position. The stepper motor's ability to move in precise steps allows for accurate positioning of the valve, which is particularly important in applications where the valve's position needs to be precisely controlled, such as in flow control or liquid level control systems.

Synchronous motors can also be used in valve actuator applications, but they are typically used in applications that require constant speed control of the valve. Synchronous motors can maintain a constant speed, which can be important in applications where the valve needs to open or close at a specific rate, such as in HVAC systems or water treatment plants.Their most representative applications include VFC (Fan Coil Unit) water valve actuators, ERV (Energy Recovery Ventilator) air valve actuators, and so on.

In summary, both stepper motors and synchronous motors can be used in valve actuator applications, but the specific motor chosen will depend on the requirements of the application. If precise position control is required, a stepper motor may be a better choice. If constant speed control is required, a synchronous motor may be a better choice.

I.CH Motion is good at upgrading the actuators of stepping motors to synchronous motors. In this way, the size of the actuators will be smaller, and the control part is relatively simple. Using micro switches can solve the actuator commutation problem. Actuator with synchronous motor is cheaper that with stepper motor .
