Novel balance is reinspected to driving method's weight

The utility model provides a novel balance is reinspected to driving method's weight, includes: step motor fixes on the frame, and the right side of instrument setting at step motor is reinspected toweight, the frame lower part sets gradually initiative permanent magnet seat, driven permanent magnet seat, initiative permanent magnet seat and step motor's spindle fixed connection, the initiative roller sets up on the base, and weight is rechecked weighing sensor and is set up by the initiative roller, its advantage is: because the vibration that step motor's motion itself produced is just verylittle, the vibration of its production is less than the vibration of being furnished with the three -phase alternating current motor production of reduction gear among the prior art, furthermore, the utility model discloses a non - mechanical contact mode of this kind of magnetic coupling is adopted in the transmission of power, and the extra interference that produces among the driving processis minimum to can improve t
