Motor Positioning Control Using a Sensorless Detent Mechanism

The patent extracts and removes the motor rotation angle sensor from the system. Instead of using a sensor to detect the rotation angle, the invention uses a detent mechanism with valley portions and mountain portions that physically constrain and indicate the rotation position through the engagement of a detent member, thereby achieving positioning without the sensor

The patent introduces a detent mechanism as an intermediary between the motor and the output shaft. The detent member engages with the valley portions and mountain portions on the detent plate, serving as a mechanical intermediary that provides positional information without requiring electronic sensors

The detent mechanism is self-service in nature, providing positional information through its mechanical structure without requiring external sensors or electronic components. The valley portions and mountain portions on the detent plate automatically engage with the detent member to indicate position, making the system self-sufficient and more reliable

The patent replaces the expensive and potentially unreliable motor rotation angle sensor with a simple mechanical detent mechanism that uses inexpensive components like springs and engagement members, achieving reliable positioning through mechanical means rather than electronic sensing

The patent extracts and eliminates the motor rotation angle sensor from the system, replacing it with a mechanical detent mechanism that provides sufficient control precision for the application while significantly reducing manufacturing costs by removing expensive electronic sensing components

The invention uses inexpensive mechanical components such as spring-loaded detent members and simple engagement surfaces instead of expensive rotation angle sensors, achieving the necessary control precision through mechanical means that are much more cost-effective to manufacture
