Various industries use industrial motors to function appropriately, so it is important that they work properly. The choice of industrial motor depends on the user, however basic knowledge is required. Each of them has a different design depending on its usage, thereby it is crucial to differentiate between each motor.
Some basic types of industrial motor include:
- AC and DC
- Brushless DC
- Gearless
- Servo
- Linear motors
It is important to be able to distinguish them separately because each varies in its application from the other. Some important fact to take notice to are:
AC and DC Motors- Advantages and Disadvantages
AC motors are one of the easiest motors to use. They are preferred because of designs and reliability to operate, and mainly because of their low financial investments. Since they are widely used everywhere, finding the replacement parts does not become a problem here. However, there are certain drawbacks as well. For example: to get proper electric motor speed control, speed controllers are quite expensive and AC motor fails to function at lower-paced speeds.
As for DC motors, they are the oldest of all the other motors. Presently, people favor using this because of its variation In a speed that serves various torque applications. However, they are more expensive and larger than AC motors. It also needs high level of maintenance and it becomes difficult to control them at lower speeds.
Gear and Stepper Motors- Advantages and Disadvantages
Gear motors are quite general in comparison to AC and DC motors. In fact, the last of the two mentioned above are easily found in the broader category. It has different types and sizes like: multiphase, induction, servo etc. if you consider using these types of industrial motors, take into account at the speed of the shaft, and the continuity of the torque, current and output power.
The last type of motor is the stepper motor, which uses a magnetic field for the rotor movement. It also works with varying stepping techniques such as: full , half or fractional steps. To change the polarity of the poles, voltage is required.
