YZP Type Motors Drive Driver

Stepper motor, YZP Type Motors as a special motor for control, is an actuator that converts electrical pulses into angular displacements. When a stepper drive receives a pulse signal, it drives the stepper motor to rotate a fixed angle (called the "Step Angle") in the direction it is set, and the rotation is run one step at a time with a fixed step angle. The angular displacement can be controlled by controlling the number of pulses to achieve the aim of accurate positioning, and the speed and acceleration of the motor can be controlled by controlling the pulse frequency, so as to achieve the goal of speed regulation and change the power order of the windings, YZP Type Motors the motor will be reversed.

Stepper motor requires the use of a dedicated stepper motor drive driver, driven by the pulse of the control unit, Power Drive Unit, protection unit and so on. The Power drive unit generates the pulse amplification of the pulse generating control unit, which is directly coupled with the stepper motor, and belongs to the power interface of the stepper motor and the microcontroller.

Control command unit, receive pulse and direction signal, corresponding pulse occurrence control unit corresponding to generate a set of corresponding phase number of pulse, YZP Type Motors after the Power drive unit to the stepper motor, stepper motor in the corresponding direction of a step angle. The pulse of the actuator determines how the stepper motor runs, as follows:

(1) m phase single M beat operation

(2) m phase Double M beat operation

(3) m phase single, double m beat operation

(4) Subdivision drive, drive signal with different amplitude value required by driver

Stepper motor has some important technical data, YZP Type Motors such as maximum static torque, starting frequency, operating frequency and so on. Generally speaking, the smaller the step angle, the greater the maximum static torque, the higher the starting frequency and operating frequency, YZP Type Motors so the operation mode emphasizes the subdivision driving technology, which improves the rotational torque and resolution of the stepper motor, and eliminates the low-frequency oscillation of the motor completely. Therefore the subdivision drive is driven to performance excellent with other types of drives.

The rotor inside the servo motor is the permanent magnet, the drive control U V W Three-phase electricity to form the electromagnetic field, the rotor rotates under the action of this magnetic field, while the motor has its own encoder feedback signal to the drive, YZP Type Motors and the driver adjusts the rotation angle of the rotor according to the feedback value and the target value.

The servo motor is also called an executive motor, which is used as an actuating component in an automatic control system to convert the received signal to angular or angular velocity output on the motor shaft. YZP Type Motors Divided into DC and AC servo motor two major categories.

Servo motor receives 1 pulses, will rotate 1 pulses corresponding angle, thus realizes the displacement, because, the servo motor itself has the function which emits the pulse, YZP Type Motors so the servo motor rotates an angle, will emit the corresponding number of pulses, so, and servo motor received pulse formed a closed loop, the system will know how many pulses to the servo motor, but also received the number of pulses back, so that the precise control of the rotation of the motor, so as to achieve accurate positioning.

In the performance comparison, the AC servo motor is superior to the DC servo motor, the AC servo motor adopts the sine wave control, the torque ripple is small, YZP Type Motors the capacity can be quite big. The DC servo motor adopts trapezoidal wave control, which is relatively poor. Brushless servo motor is better than brushless servo motor in DC servo motor.
