for 1770- and 1785-rpm induction motors. In the operating range, torque-speed characteristics are very nearly linear. If these two motors are directly coupled to the same drive drum, they are forced to run at the same speed and the 1770-rpm motor will be 50% loaded when the 1785-rpm motor is delivering rated power. Assuming equal
The maximum efficiency of a three-phase induction motor with a rotor winding is 84.6419% with a counter emf of 370.8318 V at a load current or a stator current of 5.16 A and the minimum efficiency in a three-phase induction motor with a rotor winding is 80.5003% with a large The counter emf is 369.4386V and the load current is 5.94 A.
The capacitor run induction motor working principle is the same as capacitor start induction motor. These types of motors offer good starting torque, but they may have control problems in variable speed drive applications. Single phase induction motors have problems for applications combining high power and flexible load conditions.

For an induction motor driven by a sinusoidal voltage source of adjustable amplitude and frequency, such as a pulse-width-modulation (PWM) inverter, the occurrence of sustained oscillations has often been observed when the drive is underloaded. In order to solve this problem, a linearized model is considered. The conditions under which the oscillations originate and how to determine the ...

An induction motor is often used to drive pumps, fans, conveyor belts, etc. The reason is that they're relatively cheap, reliable and capable of driving massive loads. The downside is that it's difficult to track their position which makes them unusable in accurate positioning applications.
Single-phase motors are offered for constant speed requirements. Variable speed requirements can be met by combining a three-phase induction motor with a VFD (variable frequency drive) or a single-phase motor with a TRIAC controller. Some manufacturers also offer wateright, dust-proof motors by enclosing an induction motor in a sealed case.
The principal advantage in using linear induction motors to drive conveyor belts is that force can be applied uniformly to the belt over a wide area without mechanical contact. The drive is therefore independent of the coefficient of friction between belt and rollers and belt stretch is less likely to occur. The main problem in designing a linear motor for such a drive arises from the fact ...
