What is the purpose of an AC motor?
To drive a mechanical load when supplied from an a.c. system.
What is meant by load on a motor in eletrical engineering term?
The load on a motor can be measured in watts, and it is the mechanical torque supplied, multiplied by the speed of the shaft. When the torque is in Newton-metres and the speed is in radians/second, the mechanical power output result is in watts.
How is a motor's mechanical energy able to perform mechanical work?
A motor's mechanical energy is converted into rotational motion by the motor's internal components, such as the rotor and stator. This rotational motion is then used to perform mechanical work by driving a load or system connected to the motor, such as a fan, conveyor belt, or pump. The motor's design and operation allow it to efficiently transfer its mechanical energy into useful work.
Can 3 phase 440 volt 50Hz motor run on 380 volt 50Hz supply?
Yes, But in this case the current will rise up by about 15% at full load. So if you will use the motor to drive any mechanical load take in your consideration the mechanical load Power (KW) must not exceed 85% of motor power (KW)
Is a load and a motor the same thing?
when machine is taking electrical supply and produces flux, torque etc inside and gives mechanical (rotational) output it is MOTORbut when this motor is connected to some thing which results in drawing current and work to be done, that thing is LOADwithout any load motor has maximum speed and by increasing load speed decreases..AnswerAnything connected to a supply which draws current is a 'load'. 'Heavy loads' draw a lot of current, whereas 'light loads' draw little current. So a motor represents a load to the electrical supply; this applies whether the motor is driving a 'mechanical load' or not. We use the term 'mechanical load' to describe whatever (fan, compressor, pump, etc.) is being driven by a motor.
What is the name for an electrical load that converts electrical energy into movement?
The Motor converts electrical into mechanical energy
What is the difference between a DC motor and a DC generator Why can't you use a DC motor as DC generator?
A DC motor converts electrical energy to mechanical energy. The converted energy is provided to a mechanical load.A DC generator converts mechanical energy to electrical energy. The converted energy is provided to the electrical load (voltage, current referring load).A DC motor can be used as a DC generator and vice-versa.
Why series motor should have a load?
when the load is removed the field is weakened then the speed is limited only by mechanical restraints ... (bearings, vibration, power available)
Is a motor a energy source or a load and why?
A motor is a load because it consumes electrical energy to produce mechanical energy. It converts electrical energy into rotational motion to perform work, such as moving machinery or driving a vehicle.
Why the armature current of a shunt motor decreases as the motor accelerates?
Without a mechanical load the motor accelerates until the back-emf generated by the armature nearly equals the supply voltage. On load, the speed drops and the current rises until the power taken from the supply balances the mechanical power supplied to the load. If the armature has low resistance, the speed drop under load is not very much, so speed regulation is better if the armature resistance is lower.
Why motor rating are in kw and not in kva?
Because the machines which use power i.e; load, are always rated in KW and the machines which produce power i.e generators, are rated in KVA.AnswerA motor's mechanical load is expressed in watts (horsepower in North America), so the output power of the motor must also be expressed in watts (horsepower in North America) so that the machine can be matched to its load. You cannot express a mechanical load in terms of volt amperes.
What happens to the rotor speed and rotor current when the mechanical load on an induction motor increase?
whenever the load increases,the current drawn by the motor to do or to fulfill the required energy to the load. so the current will increase generally.Increase in load will cause the full utilization of motor,so speed of rotor will decrease.
