In one embodiment, during rotor 1 electric rotary, hand rotation can be changed at any time.
In one embodiment, rotor 1 is turned manually to maximum angle, uses electric rotary instead.Now the width of the first electronic limit catch 12 or the second electronic limit catch 13 still can block the light source of the first forked type sensor 22 or the second forked type sensor 23, the assembled state of sensor can judge rotor 1 position, when first pass stepper motor drives and carries out electric rotary, rotor 1 first gets back to centre position, then calculates rotor 1 rotational angle by stepper motor.
In one embodiment, rotor 1 is turned manually, but during not to maximum angle, uses electric rotary instead.Now the assembled state of sensor has no idea to judge rotor 1 position.When first pass stepper motor drives and carries out electric rotary, rotor 1 first turns to the upwards maximum electric rotary angle of the party towards a direction, returns centre position, continues through stepper motor and calculates rotor 1 rotational angle.
Can carry out the location, direction that automatic calibration recovers motorized motions so rapidly when hand rotation destroys the positioning datum of stepper motor, this advantage of the present utility model can be applied to such as watch-dog to be needed to rotate in the physical construction of location like this.
By reference to the accompanying drawings exemplary description has been carried out to the utility model above, but practitioner certainly can not depart from scope of the present utility model carry out above-mentioned change and all other change, omit, add.
