Stepping motor with resolver (Angle sensor)

This product is equipped with a resolver (Rotation angle sensor) along with the stepping motor, enabling servo control of the motor.
We plan to expand the scope of application while maximizing the available torque from the motor.

Features

iamge : Stepping motor with resolver (Angle sensor)

Achieves "demodulation-less" motor control that does not stop even with a high load or rapid acceleration/deceleration is applied, providing smooth operation with a resolution of 200,000 P/R.
The simple structure of the resolver also contributes to durability against the outside environment. Robust manufacturing supports a motor drive with extremely stable accuracy in harsh environments such as heat, dust, shock and vibration.

Servo control via resolver eliminates the need for a demodulation margin and maximizes available torque. A usable torque 2-3 times more than from conventional products.

Torque control is performed with minimal required current, reducing power consumption and allowing for current to be cut while on stand-by. Contributes to the energy efficiency of your overall setup.

Achieves a resolution of 200,000 P/R, repeatedly providing a high level of positional accuracy and smooth drive.

The resolver is simple in structure and is resistant to disturbances such as dust, oil, heat, shock and vibration.

A torque margin is not required given a lack of demodulation. This leads to a smaller motor size.

Gear-less (decelerator), simplified cooling measures, and simplified vibration control (dampers). Helps reduce cost and design a more efficient use of space.

This device can minimize noise and vibration by providing drive control in response to the applied load.
