7. Motor Selection
DP-7022P is suitable for 3/6-wire 3-phase hybrid stepper motor. Generally
speaking, select the motor according to the torque and rated current. The torque
depends on the motor dimension. Big dimension motor has big torque. The current
depends on the resistor. Small resistor has large current and the motor will have good
performance at high speed.
For certain wiring motor, the bigger the working current, the larger the output
torque, the serious motor heating. The higher the drive power voltage, the bigger the
motor high-speed torque. The motor high-speed torque is smaller than low-speed
torque.
