YZP Type Motors Better Performance
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.
The servo motor receives 1 pulses, will rotate 1 pulses corresponding angle, YZP Type Motors thus realizes the displacement, because, the servo motor itself has the function which emits the pulse, therefore the servo motor rotates each angle, will emit the corresponding quantity the pulse, thus, and the servo motor receives the pulse to form the closed loop, The system will know how many pulses are sent to the servo motor, YZP Type Motors but also how many pulses back, so that the motor can be very precise control of the rotation, 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, YZP Type Motors the torque ripple is small, 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.
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, 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. YZP Type Motors Therefore the subdivision drive is driven to performance excellent with other types of drives.
The rotor inside the servo motor is the permanent magnet, YZP Type Motors 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 driver, YZP Type Motors and the driver adjusts the rotation angle of the rotor according to the feedback value and the target value.
Stepper motor, as a special motor for control, is an actuator that converts electrical pulses into angular displacements. When a stepper drive receives a pulse signal, YZP Type Motors 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.
