China motor gearbox factory, we are specialized in the production of motor company, product quality price concessions, our common gearbox motor speed regulation has three kinds:
1. Special frequency conversion motor, this is the use of frequency conversion of the motor to achieve speed regulation, speed range is large and continuous, high accuracy.
2. The speed-regulating motor itself has several terminal blocks. Different terminal blocks are controlled by speed-regulating switch to realize the adjustment of the motor at different speeds
3. There is also the use of governor, which is the use of mechanical means, through the different diameter of the gear bite to achieve speed regulation, this realization of the function and the second kind of similar
4. Voltage regulation and speed regulation, the voltage regulation is not the working voltage of the adjusted motor, but the excitation coil voltage, the accuracy of this speed regulation is also very high, university experiments, commonly used is this method.
One of the first and the third combination of use, in the speed regulation or more, the second and the fourth kind of general use alone, to meet the different needs of the speed regulation.
