Title:
TRAVELING BODY TRAVELING BY RECEIVING ELECTRIC ASSIST, AND ELECTRIC ASSIST METHOD OF TRAVELING BODY
Document Type and Number:
Japanese Patent JP2008072816
Kind Code:
A
Abstract:
To prevent an electric motor from being overloaded in a carrying bed with electric assist.
The carrying bed detects the number of revolutions of an assist motor 12 by using a rotation sensor 66, a CPU 61 operates a limit output by which the assist motor 12 is switched to a generator in the number of the revolutions, operates a duty output so that a current lower than the limit output is not fed, and outputs the duty output to a PWM output circuit 62. The PWM output circuit 62 applies a necessary current to the assist motor 12 by switch-controlling a switching element 64.
