Stepper motor drive mode is commonly used full voltage drive, namely walks and lock in the motor load rated voltage. In order to prevent motor over-current and improve driving characteristics, needs and current limiting resistor. Due to the lock of the stepper motor, current limiting resistor to consume large amounts of power, so the current limiting resistor should have greater power capacity, and the switch tube also have higher load capacity. Another kind of stepping motor driver is to high and low voltage driver, namely when the motor is diverted, rated or exceed the rating voltage, so that in the larger current, driven by rapid move to make motor; While in lock step is lower than the rating voltage, only let step motor winding through the lock needed for the current value. In this way, can reduce the power consumption of the resistor, and can improve the running speed of the motor, but this way of driving circuit is more complicated. The distribution of the drive pulse method that can be used hardware with pulse distributor. Now, pulse distributor has been standardized, chips, can buy in the market. But the hardware method of complex, the cost is higher also. Stepper motor control (Including the control pulse generation and distribution)Can also use the software method, which USES singlechip microcomputer, simplify the circuit already so, also reduces the cost. Using single-chip microcomputer software way to drive stepping motor, not only can programmatically, freely within a certain range of stepping motor rotation speed, rotation Angle and the rotation number of back and forth, etc. , but also convenient and flexible to control stepping motor running state, in order to meet the requirements of different users. As a result, often called the single-chip stepper motor control circuit programmable control stepper motor drives. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
