Power selection reference:
Voltage:
Stepper motor has the characteristics of torque decrease with the increase of motor speed, and the input
voltage will affect the amplitude of high-speed torque reduction. Properly increasing the voltage of the
input power supply can increase the output torque of the motor at high speed.
Therefore, if you want to get better high-speed performance, pls increase the power supply voltage of
the driver; and for low-speed applications, choosing a slightly smaller voltage can appropriately reduce
the heat of the motor.
Current:
The working process of the driver is to convert the input high-voltage and low-current power supply into
the low-voltage and high-current at both ends of the motor winding. In actual use, the appropriate power
supply should be selected according to the motor model, load torque and other factors.
The effects of regeneration voltage:
When the stepper motor is working, it also retains the characteristics of the generator. When
decelerating, the kinetic energy accumulated by the load will be converted into electrical energy and
superimposed on the driver circuit and input power supply.
Pay attention to the setting of acceleration and deceleration time to protect the driver or power supply.
When the driver is powered off, you will see the driver's LED indicator on when the load is pulled to make
the motor move, which is also affected by this.
3.3 Motor connection
The stepping motor that the 3R60 driver can match is a three-phase hybrid stepping motor with low
resistance and low inductance.
The common 3-phase stepper motor’s lead number are 3 and 6.
