Deciding which motor you want cannot be a simple task. There are different types of motors available in the market. Before you choose any, there are different parameters that have to be noticed. So how can you appropriately achieve this? Here in this article we will help you in understanding which motor is good for your work.
At start, you have to understand what voltage resource is available in your work. Electric motors can be categorized as:
- DC (Direct Current)
- AC (Alternating Current)
AC types just work on AC Voltage resource and DC types only work on DC Voltage resource. There is even a common motor that can work on both DC and AC voltages.
When you have recognized which voltage source you have you have to decide which style will work. Alternating Current motors can be further divided into:
- Single Phase Induction,
- Two Phase Servo,
- Three Phase Induction,
- Hysteresis Synchronous
Now comes to DC motors, and it is sub-divided into:
- Brush DC,
- Brushless DC,
- Stepper types.
Next we have to know the different features of each type to appropriately match a motor to its work.
One phase induction motor is linked to a single line voltage resource. An outer capacitor is needed to make this motor work. Different forms of one phase induction motors are renowned by which system they work. The four indispensable types are: capacitor start, split phase, capacitor start/capacitor run and permanent split capacitor.
A motor with split phase utilizes a switching device to cut off the start winding when the motor gets to its 75% rated speed. Even though, it has a simple design that makes it less costly for business use, it even has high starting currents and lower starting torques.
A stable split capacitor DC motors doesn’t have any switch. So, a capacitor is everlastingly connected to the winding for start. As this type of capacitor is needed for nonstop use, it doesn’t offer starting power, thus starting torques are normally low. These types of motors are not suggested for heavy applications. Though, they do have quieter operation, lower starting currents, and higher reliability/life, thus making them a perfect option for high cycle rates. These are even most consistent capacitor motor. They can even be planned for higher power factor and efficiencies at rated loads.
DC motors has lower loaded currents, higher starting, and higher competence. The disadvantage is the cost that is needed for a switching device and two capacitors. Consistency even plays an important role on account of the switching system.
The induction motor of three phases is wound for alternating voltage of three phases. These are the most rugged and simplest electric motors available in the market. The motor might be planned for either WYE or DELTA hook-up. This form is designed for constant use and high opening torques. Speed of motor is relatively stable. In case three phase voltage is accessible this is the motor to select.
