Title: Control method of motor unit, and motor unit and motor system damper equipment
Inventor: NORITAKE SEIICHIRO
IPC: F25D17/08
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To prevent generation of gear sound noise by a method, wherein a part member to be driven by a stepping motor linked with a gear ring train is installed, periods when a current does not flow are formed between drive pulses for drive a stepping motor, and a state that the part member to be driven is intermittently driven are constituted.

The stepping motor is subjected to intermittent driving, wherein intervals (a) when a current does not flow are formed between changing-over drive pulses P. Accordingly, a silent state is generated between sounds, although bounding sounds between gears exist. As a result, noise is not generated with respect in the acoustic sense.
