Abstract

DC60 (23/07/40) Power drill operation is suppressed when it is interrupted by abrupt fault such as interrupted power. And then the deficiency can be corrected Or when the coil of The electromagnet had a problem such as disconnecting after the fault was corrected with the power switch 50, still closed for insertion. Power to electromagnet And electric drills The optical power connector 38 will turn the thyristor 31 to the inductance of the transistor 35.As a result, the piercing motor 16 will not start before the The problem in the coil 27 was detected by the potential detection circuit 30 Measure the potential difference across the resistor 31 The detection of the problem that caused the thyristor 31 interrupted the inductance of the transistor. 35, according to which the electric drill will not start again. Unless it has a firm attachment By electromagnetism The operation of the electric drill is inhibited when it is interrupted by a sudden defect such as a power interruption. And then the deficiency can be corrected Or when the coil of The electromagnet had a problem such as disconnecting after the fault was corrected with the power switch 50, still closed for insertion. Power to electromagnet And electric drills The optical power connector 38 will turn the thyristor 31 to the inductance of the transistor 35.As a result, the piercing motor 16 will not start before the The problem in the coil 27 was detected by the potential detection circuit 30 Measure the potential difference across the resistor 31 The detection of the problem that caused the thyristor 31 interrupted the inductance of the transistor. 35, according to which the electric drill will not start again.
