Condition for Maximum Power of DC Motor
The DC motor is most suitable for loads that demand a higher starting torque. When DC voltage is applied to the armature, the motor is … Read more
DC Motor or Direct Current Motor
What is DC Motor? DC motor or Direct Current Motor converts electrical energy into mechanical energy. It is used to drive the mechanical loads. The … Read more
Back EMF and its Significance in DC Motor
The back EMF momentarily opposes the armature voltage when the speed of the DC motor is changed, and thus, it limits the armature current. What … Read more
Why DC Series Motor should not be Started at No Load
The DC series motor attains dangerously high speed when we run it on no load. The main reason for overspeeding is that at no load, … Read more
Starting Torque Of DC Motor
The Starting torque is the maximum torque that a motor can deliver to the mechanical load for its rotation. DC motor is capable of delivering … Read more
