Description
Technical field
The present invention relates to a kind of can be to leading, the hysteresis commutation absolute value position transducer of commutation control, power control, control from view of profit, angle control, rotating speed control, torque control, Current Control, voltage-controlled correct time of switched reluctance machines and other commutation control electric rotating machine, mainly utilize its acquisition switched reluctance machines and other commutation to control the commutation absolute position and the lead-lag commutation absolute position in correct time of multiple magnitude in correct time of electric rotating machine.
Background technology
At present; No matter known switched reluctance machines and other commutation control electric rotating machine are all only to use one group of sensing unit to form rotor-position sensor detection rotor position at motoring condition or at generating state; But; One group of sensing unit can only detect the commutation position in correct time of switched reluctance machines and other commutation control electric rotating machine, can not detect the leading commutation absolute position and the commutation absolute position that lags behind correct time in correct time of necessary multiple magnitude.So cause present high-speed motor can not export low-speed high-torque, slow-speed motor can not get into the high velocity operation, and high speed reluctance generator generating efficiency when running up is not enough.Some switched reluctance machines and other commutation control electric rotating machine adopt no approach sensor to detect to rotor position detection; But; These modes are influenced by electric machine temperature rise, circuit temperature rise etc., and detected position is not an absolute value, so motor parameter in the running will change with the variation of this underrange; Therefore, can't reach during electric operation the invariablenes turning speed state and when generating output voltage can't reach stable state.
Summary of the invention
The present invention will solve to detect leading commutation absolute position and the technical problem of commutation absolute position that lags behind multiple correct time in multiple correct time when adopting a sensing unit group to switched reluctance machines and the operation of other commutation control electric rotating machine, and a kind of multiple order of magnitude leading, hysteresis commutation absolute value position transducer in correct time is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of multiple order of magnitude leading, hysteresis commutation absolute value position transducer in correct time; Comprise the sensing unit code-disc that is fixed on the transducer cavity; Be fixed on rotating shaft that rotor is connected on position sensor signal coil; Be characterized in: non-being evenly distributed is equipped with sensing unit on the sensing unit code-disc circumference, and all sensing unit is divided into the sensing group of some identical functions, and the sensing unit code-disc is provided with the sensing channel; The sensing channel is built-in with the position signalling generation pin of position sensor signal generation dish, and position signalling generation pin is evenly distributed on the circumference of position sensor signal generation dish.
Position sensor signal generation dish and rotating shaft are tightly fixed and are one.
The sensing unit code-disc is fixed on the transducer cavity through sensing unit code-disc hold-down screw.
The transducer cavity is fixed on the electric motor end cap through the transducer hold-down screw.The diameter of bore of the endoporus of sensing unit code-disc and transducer cavity is greater than the external diameter of rotating shaft, and the external diameter of rotating shaft is connected with the endoporus of sensing unit code-disc and the endoporus noncontact of transducer cavity.
The invention has the beneficial effects as follows:
The sensing group annular that the present invention will organize identical function more is installed on the sensing code-disc, as required several sensing units is formed one group, and all the sensing group is formed array.Utilize sensing group the inequality on sensing unit code-disc circumference that be evenly distributed with identical function of position signalling generation pin on position signalling coils to distribute; Form the position deviation of corresponding each the sensing group of each pin of position signalling generation pin, utilize this deviation acquisition leading angle of overlap angle in the correct time amount or the angle of overlap angle amount that lags behind correct time.The sensing group is docile and obedient the group preface with circumference on the sensing unit code-disc, the increment magnitude of the amount of liter of this group preface or the amount of falling leading angle of overlap in formation correct time or the angle of overlap angle amount that lags behind correct time.Utilize the group preface amount of liter or the amount of falling of sensing group to obtain leading angle of overlap or the different increments of the angle of overlap angle amount that lags behind correct time in this correct time then.The increment of different magnitudes equals first order increment and multiply by magnitude.Therefore, the leading angle of overlap angle amount or the angle of overlap angle amount that lags behind correct time in correct time through selecting that different sensing groups can obtain that multiple order of magnitude has nothing in common with each other.Angle amount leading or that lag behind corresponding leading or lag behind the position in correct time, the leading commutation absolute position or the commutation absolute position that lags behind correct time in correct time that has therefore also obtained to have nothing in common with each other.
Can reach maximization to electromagnetic energy conversion through the present invention when the invention enables switched reluctance machines and other commutation control electric rotating machine to operate in the different rotating speeds section; First aspect has increased substantially the efficient of switched reluctance machines and other commutation control electric rotating machine; Second aspect makes switched reluctance machines and other commutation control electric rotating machine can when starting, obtain to be several times as much as the detent torque of nominal torque; Just can only absorb at low speed segment and obtain high torque (HT) output under the situation of small amount of electrical energy, the third aspect can make switched reluctance machines and other commutation control electric rotating machine under the work done state, obtain the speed ratio of broadness.The speed ratio of general 1:10 is increased to 1:100 at least.The whole abilities that promptly possess low-speed high-torque output and the output of high speed high power, and section can reach linear regulation at full speed.Can directly substitute the motor of various functions.Fourth aspect, switched reluctance machines and other commutation control electric rotating machine can all obtain efficient ability in low regime and high velocity under generating state.
