Controlling device of a drill for regular and reversed rotation in

The switching device of the present invention electrically connects a single-phase induction motor's starting winding to the motor's circuitry upon start-up, and disconnects it once the motor reaches a first predetermined speed. If the motor's speed drops below a second predetermined speed, the switching device reconnects the starting winding to the motor's circuitry until the motor again reaches the first predetermined speed. At start-up, diode bridge D1 turns ON, turning ON SCR S2. With the SCR ON, the diode bridge is short-circuited, drawing a large current through the bridge's a.c. side. This current flows through resistor R8, and the voltage drop across R8 is large enough to turn triac S1 ON. Thus, current flows through starting coil L2. When the motor reaches a first predetermined speed, the voltage across the starting coil is large enough to turn NPN transistor TR2 ON, turning PNP transistor TR1 ON. Accordingly, the SCR turns OFF, eliminating the large current drawn through the a.c. side of the diode bridge, and the triac turns OFF. If the motor speed dips below a second predetermined value, lower than the first, transistor TR1 is cutoff, and the triac subsequently turns back ON until the first predetermined speed is reached.

Starting winding switching circuit for single-phase induction motors

A motor starter and protection circuit is disclosed wherein a bimetallic contact support supports moveable contacts which are electrically interconnected with stationary contacts during normal non-overload conditions. Current from the power support passes through the stationary moveable contact sets as well as the bimetallic contact support and through the main coil of the motor. A positive temperature coefficient resistance is mounted on the contact support in electrical interconnection therewith. Current passes through this resistance, a TRIAC, and the motor starting winding. Conduction of the TRIAC is controlled by sensing the current which passes through the main motor coil. Only when the current passing through the main coil is substantially greater than normal load current is the TRIAC gated into conduction. A phase control capacitance is interposed between the coil sensing current through the main coil of the motor and the TRIAC gate. This capacitance ensures substantially complete conduction of the TRIAC when gated ON. The mounting of the positive temperature coefficient resistance directly on the contact support ensures good thermal transfer of the heat generated by this resistance and also maintains this resistance heated during normal operation after starting due to heat developed within the bimetallic contact support.
