Why is DC shunt motor known as constant speed motor?
Thus the final speed characteristic of a DC shunt motor, looks like. From there we can well understand this special ability of the shunt wound DC motor to regulate its speed by itself on loading and thus its rightly called the constant flux or constant speed motor.
Why DC shunt motor is termed as constant speed motor?
Hence, a DC shunt motor is able to self-regulate its speed, and can be referred to as a constant speed motor. When a load is applied to a DC shunt motor, its speed decreases, but the motor is able to self-regulate and quickly compensate for the lost speed.
Is constant speed and constant velocity the same thing?
Speed is scalar, velocity is a vector. The speed could be constant but the direction may be variable, as in circular motion. Velocity is a vector in the direction of motion with a magnitude that is equal to the speed. I can ride my motorbike at constant speed over some VERY twisty roads.
How can a car accelerate if its speed is constant?
So to accelerate all it has to do is change direction. If the car changes its direction of motion even moving with constant speed, it can accelerate. This is because, acceleration, being a vector quantity, depends on magnitude and direction both. Acceleration is the change of velocity over time.
