Coreless motors speed?
- Dec 04, 2017 -

Coreless motors in the structure of a traditional motors structure of the rotor broke through the use of non-iron core rotor, also known as Coreless rotor. This novel rotor structure completely eliminates the loss of electrical energy due to eddy currents in the core. At the same time its weight and moment of inertia greatly reduced, thus reducing the rotor's own mechanical energy loss. Due to the structural changes of the rotor motors performance has been greatly improved, not only with outstanding energy-saving features, more importantly, with the iron core motors control and drag characteristics can not be achieved. How to control the speed of the Coreless motors? The following is from Shenzhen Sinbad Motor Co.,Ltd. engineers for everyone to introduce.

Coreless electrode speed control mainly depends on the DC motors speed and voltage / load excellent linear relationship between speed, speed control method is divided into two types:

The first is the no-load speed control, and voltage-related, control the voltage of the motors size, is to achieve hollow-core motors no-load speed is the most fundamental reason;

The other is the speed of the load speed control, and the load, the speed of the load speed, the principle is that the controller receives the signal fed back by the encoder connected to the motors, through certain calculations, control and adjust the motors load Voltage or duty cycle to speed.

With the advancement of industrial technology, the application range of Coreless motors has completely deviated from the limitation of high-end products and is rapidly expanding the application scope of low-end products such as general civil to widen product quality. According to statistics, in the industrialized countries already have more than 100 kinds of civilian products on the mature application of the Coreless gear motors, Coreless motors, miniature Coreless motors!
