The common transmission component of wood engraving machine is stepping motor, which is an open-loop control element that converts electric pulse signal into angular displacement or line displacement. Although stepper motors have been widely used, stepper motors are not as conventional DC motors, and AC motors are used under normal conditions. It must be composed of a dual ring pulse signal, a power drive circuit, etc. to form a control system.
It is suitable for low-speed occasions---the speed per minute does not exceed 1000 rpm; it is best not to use the whole step state, the motor vibration is large in the whole step state, the motor step can be adjusted by the driver subdivision; the load with large moment of inertia should be Select the large frame motor.
Once the engraving machine motor is selected, the static torque of the motor is determined, but the dynamic torque is not. The dynamic torque of the motor depends on the average current (not the quiescent current) when the motor is running. The larger the average current, the larger the output torque of the motor.
