Title: Motor with electromagnetic braking - electromagnets separate braking surfaces, removal of power allows springs to operate brakes
Inventor: KOJIMA YASUHIRO
IPC: H02K7/102
Filed: 1974-06-14
Abstract: An electric motor has an automatic braking system, brought into operation once the power supply is switched off. The stator coils are arranged symmetrically around the central rotor which has a shorter axial length than the stator.
