Chiaphua Components Limited (CCL) produces high quality a.c. and d.c. motors for a wide range of applications all over the world. Our team of experienced engineers works closely with our customers throughout the project to ensure that their distinctive needs are incorporated into the designs of motors. Customers are assured that every motor delivered from CCL perfectly suits their exact specifications. With CCL's policy of continuous improvement, our company is constantly looking for ways to give customers a higher and more consistent level of quality. We also put a great deal of effort in R&D and have successfully developed several new products ready for launch in the market.

The company has newly developed three series of brushless d.c. motors for the market. Their diameters range from 38 to 50.5 mm, and lengths range from 33 to 42 mm, with various weights ranging from 135 to 333 g. They permit the operating temperature from -5ºC to 60ºC and insulation resistance is 10 Mohm at 500 V d.c. Compared with brushed motors, brushless d.c. motors have the characteristics of longer life and lower audible noise, as brush wearing is eliminated. The life expectancy is 20,000 hr at minimum, even under high rotational speeds ranging from 2,000 to 10,000 rpm, with respective power consumption 7 to 20 W. Brushless d.c. motors also consume less energy, which results in higher efficiency. High speed and good EMI level are some other advantages that make brushless d.c. motors attractive to various applications. They are widely applied in automotive industries, air-moving devices, medical equipment, and health care products.
