The control gear that aforesaid New-type electric machine rotational angle detects, it is characterized in that also comprising cpu circuit, executive circuit, cpu circuit receives the resistance value that electric resistance sensor is measured, and the resistance value scope that sets in this resistance value and the cpu circuit compared, cpu circuit is exported fill order simultaneously and is given executive circuit, when the higher limit of measuring resistance value arrival resistance value scope or lower limit, executive circuit control output shaft counter-rotation;
Aforesaid cpu circuit is the attended operation panel also;
Aforesaid cpu circuit also connects remote control circuit;
Aforesaid driving gear set comprises generator shaft gear, neutral gear, output shaft gear, and the center of generator shaft gear is installed on the motor shaft, and generator shaft gear is meshed with neutral gear, neutral gear and output shaft gear engagement;
Aforesaid output shaft is a concentric multidiameter, and multidiameter one end is thick axle, and the other end is thin axle, and thick axle forms a step with the junction of thin axle; The output shaft gear center is contained in thin axle and goes up and adjacent step, and the electric resistance sensor center is contained in the outside that output shaft gear was gone up and be arranged on to thin axle.
The present invention compared with prior art has following advantage:
As long as 1 configures the resistance value scope, just can configure rotational angle, rotational angle can configure many groups as required;
2, rotational angle can be set as required, can not cause the waste of rotational angle, and makes and come the number of times of back rotation more in the same time;
3, can rotational angle be set remote control, operation in front of not needing to go to, relatively hommization; Can certainly operate by guidance panel.
