<p>A tubular motor suitable for resistance control comprises a non-rotary cylinder body, wherein an inside of the non-rotary cylinder body is arranged with a motor, a deceleration apparatus, and a driving wheel; an output shaft and the driving wheel are connected through matching between a key and a groove, a radial width of the groove is larger than a radial width of the key, thus a transmission matching relationship with a radial slot is formed between the driving wheel and the output shaft; and the tubular motor also comprises a motor rotation sensor and a driving wheel rotation sensor, wherein the motor rotation sensor is used for detecting rotation of the motor and the driving wheel rotation sensor is used for detecting rotation of the driving wheel. Relative to prior art, the tubular motor resolves a problem that current is overlarge when the motor restarts after downlink resistance detection and resistance stuck.</p> |
