Single phase induction motor was replaced by high efficiency switched reluctance motor (SRM) in direct drive electric bench drill. The drill bit was directly fixed to the output end of the motor rotor. The belt, tower wheel and other mechanical transmission devices of traditional bench drill were omitted,and the direct drive was achieved. In order to realize the stepless speed regulation of the direct drive type electric bench drill in the full speed range, the control strategies were proposed as follows: in the starting phase, chopped current control (CCC) was used to provide high torque; in the low speed phase, a method based on sine and cosine current distribution was proposed to suppress low speed torque ripple; in the middle and high speed stage, the variable angle voltage chopping combination control method of chopped voltage control (CVC) + angle position control (APC) was used to adjust the speed and achieve smooth switching between different control modes. The experimental results showed that the proposed full speed range control strategy had high efficiency and good speed regulation performance, which could effectively improve the performance of the electric bench drill.
