Instar Stepper Driver adopts bipolar constant current chopper method to reduce the noise of the stepper motor and make the operation more stable. The increase of the driver power supply voltage greatly improves the stepper driver capability and high-speed performance of the stepper motor. When the stepper pulse stops for more than 100ms. The coil current is automatically halved to reduce the heat generated by the driver by 50%.
Instar Stepper Driver is an equal-angle subdivision stepper driver with constant torque. It is powered by a single power supply and suitable for three-phase hybrid stepping motors of various models with outer diameters of 42mm to 130mm and 3 and 6 outlets. When the pulse frequency is not high, the low speed and high subdivision can be up to 60,000 steps/rev, which improves the running precision of the stepper motor, and reduces the vibration as well as the noise.
