Siemens tumble dryer brushless motors have belts.
Siemens washing machines all have belts, but brushless motors, said the motor itself, there is no contact with the carbon brushes, and there is no belt drive is not the same thing. It's a matter of the motor itself, and as for the external output, whether it has a belt or not, that's a matter of machine design.
While brushless motors are not a substitute for brushed motors with excellent low-speed torque performance, torque and other performance characteristics, but the ease of use of brushless motors, with the trend of decreasing cost of brushless controllers and the development of domestic and foreign brushless technology and market competition, the brushless power system is in the stage of high-speed development and popularization, which has also greatly facilitated the development of the modeling movement.
Brushless DC motors are also known as DC inverter because they have the characteristics of DC brush motors and are also frequency-variable devices, and the international common term for them is BLDC. they have been widely used in many fields such as aeromodels, medical devices, household appliances, electric vehicles, and so on.

Brushless motor advantages:
1, brushless, low interference. Brushless motor in addition to the brush, the most direct change is the absence of brush motor operation generated by the spark, which greatly reduces the spark on the remote control radio equipment interference.
2, low noise, smooth running. Brushless motor without brushes, running friction is greatly reduced, smooth operation, noise will be much lower, this advantage for the stability of the model operation is a huge support.
3, long life, low maintenance costs. Less brushes, brushless motor wear is mainly in the bearings, from a mechanical point of view, brushless motor is almost a maintenance-free motor, when necessary, only need to do some dust maintenance.
