Application of Brushless DC motor in electric tapping machine
 

　　There are basically three kinds of motors for electric tapping machines on the market

　　The motor of electric tapping machine is divided into AC motor, servo motor and DC brushless motor

　　At present, AC motor and servo motor are the mainstream market in the electric tapping machine market.

　　AC motor of electric tapping machine has the following characteristics:

　　1. The motor structure is simple, easy to maintain and repair

　　2. The motor is cheap

　　Disadvantages:

　　1. The volume of the motor is too large

　　2. The motor torque characteristic is not good, and the output is too small at low speed

　　Electric tapping machine servo motor advantages:

　　1. The motor is small in size,

　　2. The motor has good torque characteristics,

　　3. Motor has constant torque mode, higher tapping efficiency

　　4. With the tapping circle number memory function, the number of companies with the same parameters will be greatly increased

　　Disadvantages of servo motor of electric tapping machine:

　　1. Hard to maintain

　　2. The price of motor is too high

　　Advantages of Brushless DC motor of electric tapping machine:

　　1. The motor is small in size

　　2. The motor has good torque characteristics

　　3. Torque mode can be selected.

　　4. It has the function of tapping circle number memory.

　　5. Cost effective
