Why cutting machine servo motor is easy to fever?

2021-01-29
Cutting machine servo motor with error no long-term accumulation, control performance is good, start, stop, reverse is done within a few pulses, and other significant characteristics of movement is not lost, so the servo motor is widely used in precision machine tools.
Is famous for its high intelligence of the cutting machine is servo motor, however, someone found cutting machine servo motor is easy to heat, this is how to return a responsibility?
the inside of a servo motor is composed of iron core and the windings. Winding resistance, electricity will produce loss, the loss is proportional to the square of the size and the resistance and current, this is what we often say that copper loss, assumes that the current is not a standard dc or sine wave, will also produce harmonic loss; Who has a 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 the machine.
so, how can we reduce the fever of the servo motor?
1, assumes that the servo motor drives have automatic half way, try to make it work in a flow state, because the motor servo motor all the calorific value of work flow.
2, assuming that the load torque range permission, can cut down the motor rated current, 5 a motor, for example, make its work in the condition of 4 a, choose low resistance, low current motor servo motor, reduce the copper loss and iron loss.
