over speed control is recommended for all prime mover driven generator to prevent over frequency operation of load connected to a system supplied by the generator and also to prevent possible over frequency operation of the generator itself from Ac system.

What is the importance of speed control of DC motor in industrial applications?

The speed control of the DC motor is important because its speed can be changed over a wide variety of simple methods which is not possible in an AC motor.


How veriable frequency drives works?

Variable frequency drives (VFDs) control the speed and torque of an electric motor by adjusting the frequency and voltage of the power supplied to the motor. They convert incoming AC power to DC, then back to AC at a variable frequency and voltage. This allows for precise control over the motor's speed and power consumption, leading to energy efficiency and optimized motor performance.


What are the advantages of using an electric motor over other types of motors?

The advantages of using an electric motor over other types of motors include higher efficiency, lower maintenance requirements, quieter operation, and better control over speed and torque.


What is advantage of series dc motor?

Advantage over?DC motors used to be preferred where precise control and variability of rotation speed were desired, but modern motor design and electronic controls have very largely negated that advantage.A series motor is useful mainly for driving a tram or bus because the torque is proportional to the square of the current. That means that a very large torque is produced for starting up and no gearbox is necessary. The motor is started with a current-limiting resistor which is switched down by the driver or automatically as the speed builds up.

What is the most efficient type of single Phase motor?

The British Lynch axial-gap dc motor. With a typical efficiency of around 90%, it can achieve the same efficiency as a 3-phase AC motor, but with far easier control over speed and torque.


If a three phase induction motor runs at a speed greater than synchronous speed?

When an induction motor is pushed over synchronous speed it will become a generator and will deliver power back to the utility.


Does coasting reduces steering control?

no but it does reduce your control over speed and braking


What type of motor is used in a starter motor?

None, it is an electric motor In fact, most cars have SERIES connected starter motors - an electric motor where the field windings (the ones that are fitted to the case of the machine and don't move) have the same current flowing in them that the armature (the rotating part of the motor) has. A series motor has very high starting torque, so it's ideal for getting a large lump of scrap metal turning over, but it has poor running (high speed) torque and poor speed control. (Speed control is so poor that if you spin up a starter motor without a load, it may over-speed and possibly throw its windings out of the armature!) Some starter motors use permanent magnets for the field system - these magnets are quite powerful and give the motor good starting torque, and magnet systems are smaller than the series coil systems, and make the starter motor a bit lighter and cheaper. These motors also have a lower top speed at no load, too.


What is the best controller for a 36v brushless motor?

The best controller for a 36v brushless motor is a brushless motor controller specifically designed for 36v systems. These controllers are optimized to work efficiently with brushless motors at that voltage, providing smooth and precise control over the motor's speed and direction. It is important to choose a controller that is compatible with the specifications of your motor to ensure optimal performance.


Can a volume control switch act as a variable control switch for a AC fan motor or a similar motor household only?

Putting a rheostat in series with a motor is not necessarily the best way to control the motor speed. The rheostat works by converting what electricity would have been going to the motor into heat. An audio rheostat would need to be sized appropriately. Putting a rheostat in series with a synchronous motor that is found in some fans is not particularly good, either. Since the motor is phase-locked with the alternating current would simply make the motor turn with less power at the same speed until it starts 'tripping over itself'. That leads to overheating. A better option is to use a solid-state motor controller. That delivers full voltage to the motor but rapidly cycles on and off. As you turn the controller up the power is more on than off.
