Technical field
The present invention relates to a kind of electric motor units, it is especially useful in electricity or motor vehicle driven by mixed power, the electric motor units have motor, its
In, motor includes stator and the rotor with armature spindle.
Background technology
Motor is generally understood as electromechanical transducer, and it can have the various methods of operation.Therefore, it can be served merely as
Electric drive serves merely as generator or alternately or is used as electric drive or is used as generator.For example, electricity or
Generator is operated in during motor in motor vehicle driven by mixed power is operated in motor running mode when vehicle is driven and in braking
In operational mode.
Operation typically for motor it is important that, it is known that what the current armature spindle by motor was transmitted is which is rotated
Torque.
It is known that the rotating torque being applied at motor directly determines via the current electric parameter at motor.
In order to mechanically directly carry out load detecting on axle, various types of torsion are it is also known to from the prior art and is passed
Sensor.It is for example arranged on armature spindle.Therefore, strain transducer (abbreviation DMS) can be arranged on axle, to detect on axle
Mechanical load.However, it is that the setting brings the disadvantage is that, DMS must be connected via holding wire with corresponding control device,
It is entity connection, so as to realize signal transmission.Especially, the contact is inconvenient in the case of the axle that can be rotated
, collector ring or similar contact interface are installed because signal transmission is necessary for.
In addition it is also known that contactless rotating torque measuring method, it is used for measuring the anti-of the rotating torque on axle
Magnetostrictive effect (inversen magnetostriktiven Effekt) (also referred to as magneto-elasticity effect (magneto-
Elastischer Effekt) or Villari effect (Villari-Effekt)).The effect it is maximum in ferromagnetic material and
It is present in the change due to mechanical stress of susceptibility.At present, such contactless rotating torque measuring method is extensive
Ground is used in the sensor bearing of Pedelec (" Pedal Electric Cycle ", the abbreviation of pedal electric vehicle).However,
The geometry of the such contactless rotating torque measuring method in the sensor bearing of Pedelec is sometimes unreliable
And/or easily disturb, because to consider sensor bearing part phase measuring, detecting respectively for rotating torque measurement
The accurate positioning of the part for rotating.This is conventionally main by the housing additional structure reality for expending high
It is existing, realize that it is made up of the low plastics of mechanical stability mostly especially by additional carrier or ferrule element.Additionally,
Problem is present in foregoing Pedelec, and contactless rotating torque measuring method is (electric to complexity on regulation technology
Change) total system in combination only high can expend ground and realize because such sensor bearing can only be passed so far
The control signal of defeated low-disturbance.Additionally, the sensor bearing is conventionally not enough to for direct environment
Electrical interference influence is shielded.
The content of the invention
It is an object of the present invention in structurally and functionally improving foregoing prior art.Especially, motor should have
There are improved rotating torque measurement apparatus.
The purpose is realized by the electric motor units of feature of the invention.Here, in the electric motor units described in beginning, nothing connects
The static part of tactile rotating torque measurement apparatus is connected with stator, and contactless rotating torque measurement apparatus rotation
Part be connected with armature spindle, and the part design for rotating is used for, and the torsion caused by rotating torque of measurement armature spindle is simultaneously
And the value of measurement is contactlessly sent at static part.
The contactless design of rotating torque measurement apparatus is bright compared with the design of the wired connection with DMS
Carry out simplifying and also improving its reliability aobviously.
In addition advantageously it is possible to control with depending on rotating torque that is measured, detecting respectively or regulation motor drive
Dynamic or recycling power.
Furthermore it is possible in the electricity or motor vehicle driven by mixed power using machine unit of the invention design, using being surveyed
Rotating torque measuring, detecting respectively carries out confidence level test to driving instruction, and the driving instruction is by driver by means of foot-operated
Power is delivered in travel board (being commonly called as " throttle ") and via so-called travel board module control device (FPM control devices)
It is transferred at motor control assembly or at the current transformer of electricity or motor vehicle driven by mixed power.In like fashion can for travel board and/
Or travel board module control device provides additional diagnostic function.
Another advantage can be that the mechanical load that be will appear from special vehicle condition is restricted on armature spindle,
To minimize the abrasion of the part of the mechanical movement of motor and/or to prevent the risk of damage at motor or adjacent component.Turn
Rotating torque on sub- axle is for example limited by means of the method realized in motor control assembly in this case.
Another advantage can be that the driving power of motor is limited on specific characteristic curve.Therefore, it is possible to for example
Via the power output of corresponding characteristic curve controlled motor, to cause to be obtained in the case of providing energy storage in energy accumulator
The distance of wheeled as high as possible, realizes so-called path coverage.
Now on the basis of the advantage of foregoing implementation, it is also possible to be that electricity or hybrid drive are equipped with rotation on armature spindle
Moment inspecting system.The instantaneous value of rotating torque can in various drive schemes, especially also in vehicle be used for control fill
Put and/or current transformer in driving regulation.Alternatively, the instantaneous value could be considered for driving on the electronics car for adjusting and examine
