7. a controlling method for magneto-rheological power drive device as claimed in claim 1, is characterized in that described controlling method is as follows: breaker closing, and connect electrical source of power, motor and controller are in holding state; DC power supply, the contact switch of driven by program controller closes, power loop contactor live line work, motor operation, and the clutch & brake coil of controller is appointed and is in power failure state, and output shaft does not turn; Start control system to working state, drive circuit produces output current, the charged generation magnetic field of clutch coil, and clutch-plate engages, output shaft running also outputting power; Output shaft running makes sensor produce feedback pulse signal, system program step-by-step counting from 0; When comparison circuit obtains P-pulse number and sensor feedback umber of pulse equal value, system program controls clutch coil dead electricity, and restraining coil is charged, now clutch quits work, break starts brake, and the switch contact of drive controller circuit restores simultaneously, and motor dead electricity also shuts down; Control program is according to the time of setting, and order power controller and motor return to initial holding state; Output shaft circular flow terminates, and circuit breaker is opened a sluice gate, and cuts off dynamic Control power supply.
8. the controlling method of a kind of magneto-rheological power drive device as claimed in claim 7, is characterized in that described controlling method is as follows:
A. time controling pattern: electrically major loop closes a floodgate, DC power supply, system starts, and relay normally open contact closes, and starts electrical source of power, motor operation; The operation time that control system sets according to single-chip microcomputer, output shaft speed current value, driving clutch coil current, clutch closes, and outputting axial power exports; When running the time value arriving setting, clutch coil dead electricity, clutch performs separation, and now relay normally open contact resets, and cuts off motor drive power supply; Now control system drives brake coil current, and break closes a floodgate, and braking output shaft, terminates Power output;
B. position control mode: electrically major loop closes a floodgate, DC power supply, system starts, and relay normally open contact closes, and starts electrical source of power, motor operation; The number of pulses that control system sets according to single-chip microcomputer, output shaft speed current value, driving clutch coil current, clutch closes, and outputting axial power exports; Control system compares the umber of pulse of setting and feedback, when the step-by-step counting of feeding back equals the number of pulses set, and clutch coil dead electricity, clutch performs separation, and now relay normally open contact resets, and cuts off motor drive power supply; Now control system drives brake coil current, and break closes a floodgate, and braking output shaft, terminates Power output;
C. loop control pattern: under the prerequisite setting interval time and cycle times, the process of a controller continuous Power output operation cycle of repetitive cycling.
