What is the speed of DC series motor at no load?
No load speed is the speed that the motor run when it has no load, i.e., the motor is separated from the engine, that speed is than greater than the rated speed, because the rated speed is the speed whwn the motor are linked to the load and it is the full load.
What is the Full load motor current of a 75KW motor?
Full load starting current is typically in the region of 5or 6 times the full load motor current;.
What does no load condition refer to?
If transformer then it refers to that, the primary is charged, but secondary is open, (no load is connected) If motor, it refers to that no load is connected to motor, the shaft is decoupled from the load, but running with out any load.
What is the nature of load connected across dc motor?
heavy load
Why dc shunt motor known as constant speed motor?
A shunt motor isn't literally constant-speed; its speed does fall between no load and full load. If you plot a graph of speed against load, you will find that the speed falls by around 10% or so. Compared with other d.c. motors, this fall is considered to be insignificant -hence the term, 'constant speed'.We apply a similar term to transformers, when we describe them as being 'constant voltage' machines. They're not literally 'constant voltage', but their regulation (difference between full-load and no-load voltage), is considered to be insignificant.
Is a switch considered a load?
No, a switch is not considered a load in an electrical circuit. A switch controls the flow of electricity to the load (such as a light bulb or motor) by opening or closing the circuit. The load is the component in the circuit that consumes the electrical energy.
How to connect a mechanical load to a motor?
To connect mechanical load to a motor, you couple it to the shaft of the motor.

What is the Full load motor current of a 75KW motor?
Full load starting current is typically in the region of 5or 6 times the full load motor current;.
Does a motor work?
A motor does not provide energy. It converts electrical energy to mechanical energy. From a circuit standpoint, the motor is considered a load (similar to a resistor). Resistors convert electrical energy to heat energy.
What does no load condition refer to?
If transformer then it refers to that, the primary is charged, but secondary is open, (no load is connected) If motor, it refers to that no load is connected to motor, the shaft is decoupled from the load, but running with out any load.
What does no load speed on a electric motor mean?
Generally a motor drives some equipment, it could be a fan, or a pump, connected to motor's shaft. The speed of the motor when no equipment is connected to its shaft is known as no load speed.
Is a motor an inductive load?
Yes, a motor is considered an inductive load because it operates by using an electromagnetic field to convert electrical energy into mechanical energy. This results in the motor drawing current that leads the voltage due to the inductive characteristics, causing a phase shift between the current and voltage waveforms.

What motor must be never run without a load connected to them?
DC Series motor should never run without load connected to it because starting torque for DC series motor is infinite and running it on no load will damage the motor due to overspeeding.
What will be the starting current of a 335hp Sqcage motor on no load?
Across the line starting of a motor can be as high as 300% of the full load amps.
