Motor single-tube rectifier energy consumption braking circuit

The working principle of the circuit: As can be seen from the figure, when it is necessary to stop, first disconnect HK, press
the stop button TA, contactor C and relay sJ will lose power and be released. At this time, the delayed
disconnection is still closed, causing the brake The contactor zc is electrically activated, and the power supply
is connected to the two-phase winding of the motor through the brake contactor, and the other end is returned to the neutral line through the rectifier tube After reaching the set
time, the sJ normally open contact is disconnected, the zc is released when it loses power, and the braking process ends. This circuit is simple and low-cost, and is often used in applications with motors
below 10 kW and low braking requirements .
