Title:
ELECTRIC SAFETY BRAKING APPARATUS
Document Type and Number:
Japanese Patent JP2009081987
Kind Code:
A
Abstract:

To provide an electric safety braking apparatus which uses a vehicular driving electric motor having a permanent magnet and allows a breaking resistor to occupy a small space.

The electric safety braking apparatus includes an electromechanical machine 10 having electric terminals 13, 14, and 15 and a permanent magnet, a resistant braking torque generating device 22, and an electromechanical current switching device 20 which surely and compactly connects the electric terminals 13, 14, and 15 of the electromechanical machine 10 to the resistant breaking torque generating device 22. The resistant braking torque generating device 22 has a bipolar assembly 122 which has two single connection terminals 124 and 126 and includes one thermal diffusion resistor that forms bipolar electric output load common to all of the electric terminals 13, 14, and 15 of the electromechanical machine 10, and a converting means 120 which converts currents from all of the electric terminals 13, 14, and 15 of the electromechanical machine 10 into a single current supplied to two single connection terminals of the bipolar assembly 122 and has no active power switch.
