Title:
MOTOR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/111440
Kind Code:
A1
Abstract:
Provided is a motor system that is capable of minimizing unneeded vibrations when starting the motor through the reduction of a torque which behaves as a reactive force acted upon the motor base by compensating the torque within the motor system. The motor system is equipped with: a dual-shaft motor (1) that has first and second rotary shafts (10a, 10b) which protrude at either end; a rotational direction conversion mechanism (2) that has an input shaft (20a), which is connected to one end of the second rotary shaft (10b) so as to receive the torque of the dual-shaft motor (1), and an output shaft (20b) for outputting the torque while rotating in the opposite direction to that of the input shaft (20a); and a flywheel (3) that is provided at one end of the first rotary shaft (10a) so as to counterbalance the reaction torque which is acted upon the output shaft (20b) of the rotational direction conversion mechanism (2) and the first rotary shaft (10a) when the dual-shaft motor (1) rotates.
