Permanent Magnetic Dc Motor

Detailed Description

(1) The system includes: Not brushes the direct current machine + driver + velocity modulation footboard, Provides the integrity, The whole debugging experiment, The performance is outstanding, Facilitates the use. (2) The electrical machinery for not brushes the structure, Does not produce the spark. Does not need to replace brushes, Protection rank: IP44, The water, The putty, The earth cannot enter in the electrical machinery, The structure compact, Overload capacity, The service life is long. (3) The load characteristics is outstanding, The low- Speed performance is good, The start torque is big, The starting current small, Meets the electric car frequent starting need, Saves the electrical energy. The electrical machinery the electrical machinery highly effective moves in the entire speed range, Compared to has brushes the direct current machine, The exchange frequency conversion electrical machinery (only in fixed spot appendix efficiency high) compares has the archery target enhancement. (4) The electrical machinery provides the high quality special- Purpose driver, Uses the high performance import power module and the upscale import control chip, Uses the technical grade primary device, The use ambient temperature - 20 degrees, The war industry level request may amount to - 40 degrees, The performance is reliable. The driver has the stepless speed regulation, Is reversing the control movement, Reverse speed halving (adjustable), Applies the brake the energy back coupling, The many kinds of overload superheat protection, The overvoltage protection, Owe press the protection, The rate signal, The voltage, The amperage output. (5) Provides the upscale velocity modulation footboard, The footboard for the non- Contact transformer structure (current price on market 300 Yuan), The footboard reliability has the archery target compared to the contact footboard or Huo Ershi to enhance, Guarantees the vehicles steady reliable movement. (6) The pulse type uses electricity, Conforms to the battery discharge characteristic, Does not need the battery instantaneous output big electric current, Prevented the battery instantaneous owes the electricity. With has brushes the direct current machine or the exchange frequency conversion electrical machinery compares, A charge may run 30%~50% course, May enhance the battery service life 50%. (7) The electrical machinery uses the jack- In rare earth magnet steel, Has specially suitably jolts, Starts repeatedly, High speed, Resists with every effort the starting greatly, Is reversing the movement need. (8) The electrical machinery rotor has the strong magnetic field, When glide and stopping generates electricity the effect to be good, Does not need to absorb the battery capacity excitation (to have brushes direct current machine or alternating current machine needs), The energy back coupling effect is good, The electric brake effect is good. (9) The electrical machinery and the driver use the forced- Air cooling or the water cooling, The temperature are low, The electrical machinery uses the import oiliness high speed bearing, Exempts the maintenance, The reliability is high, The electrical machinery life is long. (10) The electrical machinery has the horizontal type, The hanging, May bring raised along to stop the mouth end cover, May use the double axle elongation, The spline axle elongation, May act according to the entire vehicle request and the rear axle of car parameter request quantity body makes to order each kind of voltage, Each kind of rotational speed, Each kind of power request electrical machinery, May make the electrically operated electricity generation dual purpose electrical machinery.
