The precision of the servo motor is determined by the precision of the encoder (line number). Motor servo motor is also called the implementation, in the automatic control system, is used as actuators, converts the received electrical signal into angular displacement or velocity of motor shaft output. Divided into two www.dongfeng- motor.com major categories of dc and ac servo motor, its main characteristic is, when the signal voltage is zero no rotation, speed decreases with the increase of torque and uniform ac servo is better, because it is squirrel cage induction motor a sine wave control, torque ripple is small. Dc servo is trapezoidal wave. But dc servo is simpler and cheaper.

With sine wave of equivalent continuous rectangular wave pulse sequence midpoint overlap (pictured above), in this way, by N continuous and wide range of rectangular pulse waveform with the positive half cycle of sine wave equivalent. Also, sine wave of negative half cycle can be equivalent with the same method. Figure 3 (b) a series of pulse waveform is expected by the PWM inverter (Pule Width Modulation) waveform. Because of the pulse amplitude is equal, so the inverter can be made of a constant dc power supply.

That electric motor price is to say, this kind of hands has been a make inverter in the inverter adopts uncontrolled diode rectifier. Inverter output pulse amplitude is the output voltage of the rectifier. Such as inverter all switching devices are working under ideal state, to drive the corresponding signal switching device should also be similar to figure 3 (b) the shape of a series of pulse waveform. As a result of the PWM output voltage waveform and current waveform is sine wave, with many higher harmonic components, which makes the energy input to the motor cannot be fully use, increase the wear and tear. In order to make the output waveform similar to sine wave, sinusoidal pulse width modulation (SPWM) is proposed. So-called SPWM modulation, simply speaking, is in the pulse width modulation, the duty ratio of pulse sequence shall be carried out in accordance with the law of sine wave of change, that is, when the sine wave amplitude is maximum, the pulse width is the largest also, when the sine wave amplitude is the minimum value, pulse width and minimum (as shown in figure 4). In this way, electricalmotor1.blogspot.com the output pulse sequence can be made to the motor load greatly decreases, and the higher harmonic current component to improve the efficiency of the motor. SPWM waveform is sum up the features of "continuous range wide, two narrow middle wide".

Dc motor performance is closely related to its excitation mode, dc motor excitation method usually has four kinds: single phase motor dc separately excited motor, dc shunt motor, dc series motor and dc compound motor. Master way of four characteristics: 1, dc separately excited motor: exciting winding and armature contact without electricity, excitation circuit is made up of other dc power supply. So the field current is not affected by the armature terminal voltage or armature Three phase motor current. 2, dc shunt motor, shunt winding ends voltage is the voltage on both ends of the armature, but exciting winding with fine wire coils, the number of turns a lot, so has larger resistance, made by his exciting current is small. 3, dc series motor: exciting winding is series and the armature, so this kind of motor with the change of the armature current in the magnetic field have obvious changes. In order to electric generator make the field winding does not cause big loss and voltage drop, exciting winding resistance as small as possible, so direct current series motor is usually use coarser wire coils, his less number of turns. 4, compound motor: dc motor flux produced by the two winding excitation current.
