Title: Drive motor
Inventor: SHIBAZAKI MASANORI
IPC: E06B9/72
Filed: 2000-04-21
Abstract: PROBLEM TO BE SOLVED: To facilitate drive control, at the same time, simplify the configuration for miniaturization, and improve reliability by actuating a brake device through centrifugal force being between the rotor shaft and the fixing case of an electric motor for driving a winding member. SOLUTION: When an electric motor 3 has a light load and rotary speed becomes excessive, an elastic thin plate piece 10-2 of a brake device 7 is displaced toward the outside in a radius direction from a position, in contact with the outer-periphery surface of a boss 8 due to a centrifugal force, and a permanent magnet piece 10-3 approaches a conductor part 10-4 via a small gap. Thus an eddy current is generated on the conductor 10-4, allowing the magnetic flux by the eddy current to act on the magnetic flux of the permanent magnet piece 10-3 for attracting the permanent magnet piece 10-3 to the conductor part 10-4, applying damping force to the electric motor 3, and preventing excessive rotation.  When the electric motor 3 is rotated normally, the elastic thin plate piece 10-2 is placed onto the outer-periphery surface of the boss 8, thus preventing brake operation from being generated.
