Learn About Different types of motors and their use

You must have observed that while purchasing a motor base, it’s often asked which technology is better, AC or DC, but the fact behind it is that it is application and cost dependent.



AC Motors

In many features including speed control, AC motors are highly flexible, and compared to DC motors they have a much larger installed base.

A few of its key benefits are:

  • The torque limit needs to be adjustable
  • Controlled acceleration
  • Operational speed should be adjustable
  • Controlled starting current
  • At the start, it demands low power
  • Reduction in power line disturbances

There are two types of AC motor:

Synchronous

The rotation of the rotor is synchronized with the frequency of the supply current in this particular type of motor and under varying loads, the speed remains constant. Hence at a constant speed, it is ideal for driving equipment, and in high precision positioning devices like robots, instrumentation, machines, and process control they are used by many motor base suppliers.

Induction (Asynchronous)

Electromagnetic induction from the magnetic field of the stator winding produces an electric current in the rotor and hence Torque is used by this type of motor. These are the most common type of AC motors and are essential for the industry due to their load capacity along with Single-Phase induction motors that are being used. You will find that Three-Phase induction motors are used more in industrial applications including pumps, conveyor systems, compressors, and lifting gear.

DC Motors

The first type of motors widely used are the DC motors and compared to AC systems the system's initial costs tend to be typically less than for low-power units. But with a higher power, the cost of overall maintenance increases and it needs to be taken into consideration. By varying the supply voltage the DC Motors' speed can be controlled.



Its Advantages are-

  • Linear speed-torque curve
  • Speed control over a wide range
  • Quick Starting, Stopping, Reversing, and Acceleration
  • High Starting Torque
  • Easy installation

There is wide use of DC motors by motor base manufacturer and you can find them in small tools and appliances, through to electric vehicles, lifts & hoists.

Greenhouse Motor and its Benefits

Image
By maximum  greenhouse motor ,  Mechanical torque is developed by the conductors carrying current interaction in a right angle direction at to a magnetic field. You will find a difference in various types of electric motor in how the conductors and the field are arranged and also in the control that is executed over output speed, torque, and position. By alternating (AC) current or direct current (DC) the greenhouse motors are powered. The development of DC motors was done first and has certain advantages and disadvantages. Every motor works differently but all of them utilizes the power of the electromagnetic field. Before moving on to the different types of motors we need to know about the very basic principles of electromagnetic fields in motors. A secondary and primary winding (magnet) is used by AC electric motors, the primary one is attached to AC grid power (or directly to a generator) and is then energized. From the primary, the energy is received by the secondary ...

Working of Worm Gears and its Uses

Image
For nonparallel, nonintersecting, right angle gear drive system applications where there is a requirement of high transmission gearing ratio, there comes the wide use of worn and wheel gears. worm gearbox and reducers generally give you a more compact solution when you compare them with other gear, belt, and chain transmission elements. In certain configurations, you will observe that a worm and wheel gear set can provide you sufficient high friction to become self-locking which can be an apt feature if a defined position is needed for a gear train if it is not braked or unpowered. With right or left-hand threads and teeth the manufacturing of worms and worm gears is done. The determination of the hand of a worm or worm gear can be done by observing the direction in which the threads or teeth lean when the worm gear has positioned the hole facing upwards. You will find that in the worm and gear there are the same pitch, number of threads, hand, and tooth dimensions. They sho...
