Why do we Need a starter in DC motors?
While starting a DC motor huge amount of current can be driven to the windings due to the absence of the back emf. The current may rise about 4-6 times higher than the rated load current...

DC motor direction control using relay circuit
A Relay based DC motor controller works with an H-bridge arrangement. With an H-bridge circuit, the polarity across a load can be altered in both directions. In the Dual SPDT motor driver circuit, the...
Why a capacitor is used with a single phase fan or motor?
A single phase induction motor is not a self-starting motor, so it requires some starting means for working. That is an initial torque is required for the motor to get started. The starting torque can...
