1.The work principle of induction motor- - Introduction Induction motors, also called induction motor, the motor is an AC rotating, and the rotation of the rotor rotating torque obtained at the rotating magnetic field. It has a simple structure, easy maintenance, lower cost, higher efficiency, better operating characteristics and other characteristics of people's daily life, the most widely used motors, used for a variety of mechanical equipment, household appliances to power, such as machine

Single phase asynchronous motor principle - Introduction

posted by

Single-phase asynchronous motor is a kind of can convert electrical energy into mechanical energy device, usually the case, the capacity of a single-phase asynchronous motors are relatively small, only single-phase power supply, easy to use, widely used in industry and agriculture and live electrical appliances field, typical applications include: washing machines, electric fans, refrigerators, air conditioners, pumps, blowers, juicer, soybean milk and so on.

1. Removal of the old winding electric motor: These are basically single-phase four-pole rotor motor sixteen slots. Remove fixed, four screws and the lower end of the stator core, the stator core together with winding can be removed, but turn the leaf fan, Bishan, a small desk fan, the lower cap would buckle in the middle of the core, the core which is difficult to remove, first from the two end caps with a screwdriver to pry open the seam, remove a cap; core card in the other end cap in with a

Air compressor motor burned Case Analysis - Compressor vacuum

Open-type refrigeration compressor has been forgotten, but the refrigeration industry and some field personnel retained habits of the past - with a compressor evacuated. This is very dangerous.

Air compressor motor burned Case Analysis - inadequate cooling

posted by

Power compressors are generally larger return air cooling type. The lower the evaporation temperature, mass flow system often smaller. When the evaporation temperature is low (more than the manufacturer's instructions), the flow is not sufficient to cool the motor, the motor will operate at higher temperatures. Air-cooled compressor (usually no more than 10HP) dependence on a small back to the gas, but the compressor ambient temperature and cooling air flow have specific demands.

Air compressor motor burned Case Analysis - power phase and voltage anomalies

posted by

Abnormal voltage and phase can easily destroy any motor. Supply voltage range must not exceed the rated voltage of ± 10%. Three phase voltage imbalance must not exceed 5%. High-power motors must be independent of the power supply, resulting in low voltage to prevent the same line when other power equipment up and running. Motor power cable must be able to carry the rated motor current.

Air compressor motor burned Case Analysis - Contactor issue

posted by

The contactor is one of the most important components in the motor control circuit, it can destroy the best selection of unreasonable compressor. Press contacts load the correct choice is extremely important.

Air compressor motor burned Case Analysis - short circuit caused by metal debris

posted by

Inclusion winding metal chips are short circuit and ground insulation value is low culprit. Vibration during normal operation of the compressor, as well as every time you start winding by electromagnetic force and twist, will promote inclusion in between the winding and winding enameled metal shavings between the relative movement and friction. Sharp edges will scratch enameled metal shavings insulation, causing a short circuit.

Air compressor motor burned Case Analysis - Abnormal load and stall

posted by

Motor load including compressed gas required to load and load needed to overcome mechanical friction. Compression ratio is too large, or the pressure is too great, the compression process will be more difficult; and friction lubrication failure caused by increased and motor stall in extreme cases, will greatly increase the electrical load.

Water pump motor

Classification by structure should be divided into horizontal and vertical electrical motors. Due to the operating characteristics of the pump is relatively small starting torque, starting frequency is relatively small, relatively long time continuous operation characteristics, and therefore the majority of the pump motor rotor squirrel cage induction motor or a synchronous motor.
