Optionally, energy feedback module is switch magnetic group formula motor.
Specifically, switched reluctance machines are a kind of buncher, and the buncher has direct current, two class governing systems of exchange concurrently
Advantage, be the stepless time adjustment system of new generation after frequency conversion speed-adjusting system, Speed Regulating System of Brushless DC Motor.Its structure letter
Single firm, speed-regulating range width, speed adjusting performance is excellent, and all has greater efficiency in whole speed adjustable range, and system reliability is high.
Further, the switch magnetic group formula motor mainly includes switched reluctance machines, power inverter, controller and position
The part of detector four constitutes.
Wherein, comprising power inverter and control circuit in controller, and position detector is then installed in one end of motor.
Switched reluctance motor drive system combines Induction motor drives and the transmission of direct current drive electric motor of automobile
The advantage of system, is the contenders of these drive systems, and its major advantage is as follows：
1st, switched reluctance motor has larger utilization factor of motor, can be the 1.2 of induction conductivity usage factor
~1.4 times.
2nd, the simple structure of motor, without any type of winding on rotor；There was only simple concentratred winding on stator,
End is shorter, without alternate jumper.Therefore, with manufacturing process is few, low cost, reliable operation, a little repair the features such as.
3rd, the torque of switched reluctance motor is unrelated with current polarity, it is only necessary to unidirectional current excitation, ideally common ratio
In translation circuit per mutually can only with a switch element, and with motor windings in series, will not as PWM inverter power supply that
, there is the straight-through danger of two switch elements in sample.So, Switch reluctance motor driving system SED circuit is simple, reliability
Height, cost is less than PWM Alternating Current Governor Systems.
4th, the version of switched reluctance motor rotor limits little to rotating speed, can be made into pot-motor, Er Qiezhuan
The rotary inertia of son is little, can at any time change the size and Orientation of phase circle torque again in each commutation of electric current, thus system has
Good dynamic response.

Control by the conducting to electric current, disconnection and to amplitude, is met the mechanical property of different loads requirement, it is easy to accomplish be
The functions such as the soft start and four quadrant running of system, control is flexible.Again because SRD systems are self-synchronizing system operations, will not be as becoming
There is like that unstable and oscillation problem in low frequency in the induction conductivity of frequency power supply.
6th, because SR switched reluctance motors employ the structure and method for designing of uniqueness and control skill accordingly, its
Processed in units can compare favourably with induction conductivity, or even also hold advantage slightly.The efficiency and power density of SRD systems is in broadness
Teaching level can be maintained in speed and loading range.
