1, use and resistance of driving of stepping motor winding use coarse wire, coil resistance value Rw is very small, as shown. In each phase coil series external resistance R, in order to limit the current small dry rated current of the winding through the I. Winding through the current limiting method. Can be used to reduce the power supply voltage and type external electric limited R two methods. 2, no additional resistance of driving a stepper motor only run at low speeds, don't need additional resistance, coil directly made constant voltage power supply voltage and power semiconductor drive, the stepping motor of wire radius around a finer, more number of turns, the resistance value is larger, the method for small current drive mode. 3, voltage driver driving a stepper motor is used when applied voltage, the way such as shown in figure. When the driving voltage is 24 v, to stop running after location, its switch voltage is 5 v, the power loss is reduced. This is the second voltage control mode. Can also according to the types of load, to maintain the positioning accuracy, a little current. Another way is to. At low speeds with low voltage control, and high speed, namely above a certain speed switch to high voltage driven approach. 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.
