Cutting machine servo servo motor is how to maintain?

Servo motor is a kind of electrical pulses into angular displacement of the actuator. Popular point: cutting machine when the driver receives a pulse signal, it is driven by servo motor according to set the direction of a fixed point ( The Angle) 。 You can by controlling the pulse number to control the amount of angular displacement, so as to achieve the purpose of accurate positioning; At the same time you can control the pulse frequency to control the servo motor rotation speed and acceleration, so as to achieve the purpose of regulating.





the cause of the servo motor fever: for all kinds of servo motor, the internal is composed of iron core and winding coils. Winding resistance, electricity will produce loss, loss is proportional to the square of the size and the resistance and current, this is the copper loss, we often say that if the current is not a standard dc or sine wave, will also produce harmonic loss; Core has hysteresis eddy current effect, also can produce loss in the alternating magnetic field, its size and material, current, frequency, voltage, this is called iron losses. Copper loss and iron loss will be displayed in the form of heat, which affects the efficiency of servo motor.

servo motor rotor of permanent magnet, when current flows through the stator winding of the stator winding is a vector field. The magnetic field can drive the rotor rotating an Angle, make a pair of rotor magnetic field direction in line with the stator magnetic field direction. When the vector magnetic field of the stator rotating an Angle. Also as the rotor magnetic field to turn an Angle. For every input electrical impulses, a rotary Angle of motor before further. Its output angular displacement is proportional to the input pulse count, speed is proportional to the pulse frequency. Changing the order of the winding current, servo motor will be reversed. So the available control pulse number, frequency and various phase winding of the motor power in order to control the servo motor rotation.

servo motor is its application advantages compared with traditional rotating servo motor

1. Speed and high acceleration;

2. High precision;

3. No mechanical wear, long service life;

4. Drive system has simple structure, high efficiency;

5. Low noise, quiet operation.
