A Scottish monk called Andrew Gordon made the first motor in the 1740s. Since then, motor technology has greatly revolutionized. Integration of components, increased efficiency demands, and new areas of applications have resulted to progress in electric motors technology.
There are different kinds of motors. Differentiating factors include size, design, rating, and torque. Some motors are small while others are large. Watches have small motors. Usage of the large motors includes pumped-storage applications, pipeline compression, and ship propulsion. A big motor will have a rating of up to 100 megawatts and a torque exceeding 10,000 N-m.
The primary purpose of an electrical motor is to convert electrical energy into mechanical energy. On the other hand, a generator does the reverse. A motor produces linear force otherwise called torque. It functions differently from loudspeakers and magnetic solenoids. These devices convert electricity into motion. However, the motion produced does not have usable mechanical power. Custom motors and the typical varieties get their power from AC or DC sources.
Large and small motors have a number of components. These include rotor, stator, air gap, and windings. The stationary part of the electromagnetic circuit of a motor is the stator. It comprises of either permanent magnets or windings. This part of the magnet helps to reduce energy loss. The moving part of the motor is the rotor. It has conductors that deliver current to the stator. The current will interact with the magnetic field and subsequently turn the shaft.
There is need to buy the right type of motor. For high level of performance, accuracy, and productivity, there is need for high torque motors. Unique industrial and commercial applications will require custom motors. A manufacturer can custom make a motor to fit particular industrial requirements.
Most electrical and mechanical appliances have motors. Vacuum cleaners, air conditioners, fans, TV sets, radios, and computers, have motors.
