4 Poles Aluminium Housing Three Phase Asynchronous Induction AC Motor For Reducer

3 Phase Induction Motor PRODUCT DESCRIPTIONS

Three-phase asynchronous motors can be considered the most reliable electrical machines: they carry out their function for many years with reduced maintenance and adapt themselves to different performances according to the requirements of both production and service applications.

Their applications are fit in the most different industrial sectors, such as food, chemical, metallurgical industries, paper factories, or water treatment and extractive systems. The applications concern the equipment with machine components running at a fixed or variable speed, such as example lifting systems such as lifts or suitable hoists, transporting systems like conveyors, ventilation, and air conditioning installations, without forgetting the most familiar use with pumps and compressors.

PERFORMANCE CHART

How to troubleshoot common motor faults

1. After the motor is switched on, the motor cannot start, but there is a buzzing sound?

1) The power is not turned on for a single-phase start;
2) Motor overload;
3) Stuck by the dragging machinery;
4) The open-circuit of the rotor circuit of the wound motor is broken;
5) The internal end of the stator is connected incorrectly, or there is a disconnection or short circuit

Second, the motor is difficult to start. After the rated load is added, is the speed low?

1) low supply voltage
2) The original angle connection was wrongly connected to the star connection
3) The cage end of the squirrel cage rotor is unsoldered, loosened, or broken

Third, the heat exceeds the temperature rise or smoke after the motor starts.

1) The power supply voltage is too low, the temperature rise of the motor is too high under the rated load;
2) The motor is poorly ventilated, or the ambient humidity is too high;
3) Motor overload or single-phase operation;
4) The motor starts frequently, or the number of forwarding and reverse rotations is excessive;
5) Stator and rotor want to wipe

Fourth, low insulation resistance.

1) The winding is wet or drips into the motor;
2) There are dust and oil on the windings;
3) The stator winding insulation is aging.

Five, the motor shell is charged.

1) Insulation of motor lead-out or insulation box of the junction box
2) The winding end touches the casing
3) The motor casing is not reliably grounded

Six, the sound is abnormal when the motor is running.

1) The stator winding is misconnected, a local short circuit or grounding causes the three-phase current to be uneven and cause noise
2) There is clothing inside the bearing, or there is a severe lack of lubricant

Seven, motor vibration

1) Motor installation foundation is uneven
2) Motor rotor imbalance
3) Unbalanced pulley or coupling
4) Shaft shaft bend or eccentric pulley
5) Motor fan imbalance
