Motor Turn Stall Detector

Schematic Diagrams      Comments Off on Motor Turn Stall Detector

In single phase AC induction motors, often used in fridges and washing machines, a start winding is used during the starting phase. When the motor has reached a certain speed, this winding is turned off again. The start winding is slightly out of phase to the run winding. The motor… Read more »

Over Voltage Protection

Schematic Diagrams      Comments Off on Over Voltage Protection

Safety devices like fuses provide protection against excess current, but do nothing for transients and short duration spikes of high voltahe on the power supply lines.This circuit uses the “crowbar” method and provides fast protection against transient voltage spikes, transients that could cause damage to sensitive components. The thyristor will… Read more »

Over voltage and low voltage protection circuit

Schematic Diagrams      Comments Off on Over voltage and low voltage protection circuit

This is an electrical circuit protection device sound disappeared, when too much voltage 220V, and protection, when pressure is too low with Using the relay cut off power when voltage problems. From the circuit when the voltage is 220 volts AC through a transformer T1. It serves to reduce the… Read more »
