how to make a waste stator rotor motor for environment protection

TEMPERATURE PROTECTION METHODS OF INDUCTION …

Induction motor temperature protection monitors the stator winding temperature by directly measuring the temperature using embedded temperature detectors. There are different types of temperature detectors (sensors), that are used for electric motor protection thermostat, PTC thermistor, resistance temperature - detector (RTD), thermocouples.

Motor Protection Principles 101308 - L 3

A motor can run overloaded without a fault in motor or supply A primary motor protective element of the motor protection relay is the thermal overload element and this is accomplished through motor thermal image modeling. This model must account for thermal process in the motor while motor is starting, running at normal load, running

motors, the windings placed in the laminated stator cor e produce the mag-netic field. The aluminum bars in the laminated rotor core are the current-carrying conductors upon which the force acts. The resultant action is the rotary motion of the rotor and shaft, which can then be coupled to various devices to be driven and produce the output.

Induction motor-types of induction motor – parts and …

Pay attention; the rotor rotates over a period from the stator which means that there is a lagging of flux current. The flux current in the rotor lags the flux current in the stator so the rotor will never reach it’s rotation magnetic field speed (the synchronous speed). Types of the induction (asynchronous) motor:
