1st, design characteristic

* Comprehensive substitution direct current machine, comprehensive substitution alternating current machine + vector control, comprehensive substitution alternating current machine + direct torque control, comprehensive substitution switch magnetic resistance electrical machinery

 * The low speed great torque, the initial firing current is small, conforms to the electrically operated vehicles load characteristics, does not need the margin of power

 * The intermittence uses electricity, conforms to the battery discharge characteristic, saves the battery capacity, enhances the battery life

 * Not brushes the structure, the air cannot enter in the electrical machinery, suits the rain putty dust environment, the reliability is high

* The rotor uses the embedded magnet steel, conforms to the electrically operated vehicles to jolt, the big start torque, high speed, is reversing the movement and the weak magnetism velocity modulation need

* The strong permanent magnetism structure, the brake and the energy feedback performance is good, does not need the excitation, the increase gathers drives the course

* May make the wheel hub electrical machinery, use the electronic meeting and parting index error fast

* The volume small, strives in a big way, the efficiency is high

 * May omit the speed reducer drive, the economical volume

* May make the electrically operated - charge dual purpose machine

* Does not have the radio disturbance, does not produce the spark, suits specially in the explosive place
