Direction of Rotation of DC Motor
The Direction of rotation of the DC Motor can be reversed by reversing the direction of torque of the motor. When the motor exerts torque
DC Motor
Working or Operating Principle of DC Motor
The DC motor converts electrical energy into mechanical energy. The input power to the DC motor is DC power. The DC motor works on the
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
Losses in DC Machine – Types of Losses
What is a DC Machine? A Direct Current (DC) machine operates using direct current (DC) to either: These machines play a crucial role in various
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
Back EMF in DC Motor – Definition, Formula & Significance
The back EMF momentarily opposes the armature voltage when the speed of the DC motor is changed, and thus, it limits the armature current. Definition
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,
DC Shunt Motor : Construction, Speed Control & Characteristics
A DC shunt motor is known for its nearly constant speed operation, making it ideal for applications like lathes, fans, and conveyors. In this post,
Why DC Series Motor Is Ideal for Driving Heavy Loads
A DC series motor is widely used for driving heavy loads due to its unique ability to produce very high starting torque. This article explains
IR Compensation in DC Drive
IR compensation is an essential feature in DC drives and VFD to ensure speed regulation, especially when tachometer feedback is unavailable. The following sections explain
