PURPOSE:To prevent a motor from burning without adding a protecting circuit by providing a fuse to be melted by an overcurrent due to the trouble of an inner winding or a motor driving element in a motor structure frame. CONSTITUTION:When a motor driving element 1 is short-circuited, a large current flows in an inner winding 5, and it is burned, but before burning, a fuse 9 is melted by heat generation due to the large current to protect the motor against burnout. Even if the winding 5 is short-circuited, a large current flows, but the fuse 9 is similarly melted to protect the motor against the burnout. |
