42 stepper motors can use 12v2a power?
Stepper motor is an induction motor, its working principle is the use of electronic circuit, the DC power supply variable components, multi-phase timing control current this current stepper motor power supply, stepper motor can work normally, the power supply for the stepper motor driver is divided into the multi phase sequence controller.Although the stepper motor has been widely used, but stepper motors can not be like ordinary DC motors, AC motors in the regular use. It must be composed of double ring pulse signal, power drive circuit and so on, and the control system can be used. Therefore, it is not easy to make good use of stepping motor. It involves many specialized knowledge, such as mechanical, electrical, electronic and computer. Stepping motor, as an actuator, is one of the key products of mechatronics. It is widely used in various automatic control systems. With the development of micro electronics and computer technology, the requirement of stepping motor is increasing day by day, and it is applied in every national economic field.
Stepper motor power supply voltage is less than 5 times the rated voltage of motor, not less than 2 times the rated voltage work.Stepper motor voltage is very low, but the drive voltage is generally 8~48V interval, the smaller voltage may cause high-speed torque shortage. The starting frequency is low.But the current of the power supply is not less than 80% of the rated current (the following form). This power source can drive two YPF4210A34D or two YPF4215A40D, and can only drive one YPF4220A49D.
42 stepper motor can use 12v2a power supplyThe stepping motor is an open loop control element which transforms the electric pulse signal into angular displacement or linear displacement. In the case of non overloaded, the motor speed and stop position depends only on the pulse frequency and pulse number, regardless of load changes, when the stepper driver receives a pulse signal, it drives stepper motor to set the direction of rotation of a fixed angle, called "step", it is the rotation of the fixed point of the operation step by step. Number of pulses can be controlled by controlling the angular displacement, so as to achieve the purpose of accurate positioning; at the same time by controlling the pulse frequency to control the motor rotation speed and acceleration, so as to achieve the purpose of speed.
