INDUCTION MOTOR, GEARBOX, INVERTER

An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. An induction motor can therefore be made without electrical connections to the rotor. An industrial gearbox is a system in which the mechanical energy is transferred from one device to another and is used to increase torque while reducing speed. Gearboxes can modify their speed, torque to convert energy into a compatible format. They are useful in easing out the mechanical functioning in industries. An inverter controls the frequency of power supplied to an AC motor to control the rotation speed of the motor, without an inverter, the AC motor would operate at full speed as soon as the power supply was turned ON. You would not be able to control the speed, making the applications for the motor limited. The use of an inverter to adjust the speed and acceleration of an AC motor increases the range of applications of the motor compared with a motor that operates at a constant speed. The speed of a motor is normally measured as the number of revolutions per minute (rpm). The acceleration rate is given as the change in speed over a specific period of time.
