Induction Motor With Star Delta Starter

Induction motor with star delta starter is widely used in factory equipment, such as in air conditioning rooms of shopping malls or pump stations of water plants. In our daily life driving equipment, their application is also very extensive. In these places, you will always hear a buzzing sound.
As the demand for energy conservation and precise control continues to increase, a frequency converter, a regulating device, has been added to the motors.Applications in manufacturing: driving conveyor belts, mixers, compressors and machine tools.
In air conditioners, the water chillers and cooling fans as well as the core fans all require Induction motor with star delta starter.
In water treatment, pumping, water delivery and wastewater treatment all require motor-driven operations.

Take the frequency-driven central air conditioning system as an example.
In the past: the refrigeration pump motor of the system was directly connected to the power grid and operated at the maximum speed throughout the day. Engineers needed to control the water flow by adjusting the valve opening, which was like constantly stepping on the accelerator and then using the brakes to control the speed - a lot of energy was wasted on the valves.
Now: After installing the VFD, the system can smoothly adjust the speed of the pump motor according to the real-time cooling load of the building. Since the power consumption of the pump is approximately proportional to the cube of the speed, a slight decrease in speed can bring about significant power savings.

In May 2025, I received a 75KW motor for an adapter compressor from a customer in Zimbabwe.
Induction motor with star delta starter usually requires custom dimensions, and all dimensions need to be precisely measured.
However, since the motor was always running, we had to wait for the factory's work schedule. Measurements could only be taken when it was stopped. The customer completed the measurements two months later. After our engineers spent two days designing, the complete design drawings were finally completed. Considering the load of the compressor, the service factor needs to reach 1.15. This is to ensure that the motor does not experience "temporary overload" when running. The load of the compressor is not constant and may encounter overload situations.
Long-term operation is more durable: reducing "full-load losses"
A service factor of 1.15 means that this motor can drive a 75KW load with an 86KW capacity. The operating load rate is only 87%, with lower temperature rise, less insulation and bearing losses, and higher reliability during long-term operation. The lifespan is usually 20-30% longer.
At the same time, it can be adapted to more harsh environments.
At present, our customers have received the motors. After replacing the Induction motor with star delta starter, the compressor is operating well and the motor is working stably. The customers highly approve of the quality of our motors.
