摘要:
Systems and methods that determine resonant frequencies of a motor system via employing an output of a velocity regulator. The velocity regulator enables the motor drive to command the rotation of the motor at predetermined rotations, by setting rotational speeds of the motor. The output of the velocity regulator can then be stored as a function of time, and a Fast Fourier Transform performed on such time data to obtain a frequency data and a signal power spectrum.

A backlight assembly and a liquid crystal display device can discharge heat from the lamp unit to the outside or effectively dissipate the heat. The backlight assembly of the present invention includes a lamp unit, a receiving member for receiving the lamp unit, a first heat dissipation member disposed below the receiving member, and a second heat dissipation for wrapping around a lateral side of the receiving member and the first heat dissipation member. The lamp unit is disposed on an area corresponding to the lateral side of the receiving member. In one embodiment, the first heat dissipation member is a flat plate made of graphite and disposed on an outer side of the bottom of the receiving member. The second heat dissipation member is metal with good thermal conductivity in close contact with the first heat dissipation member and the lateral side of the receiving member where the lamp unit is disposed. Thus, the heat discharged from the lamp unit can be distributed uniformly over the entire area of the receiving member. In addition, the lateral side of the receiving member where the lamp unit is disposed can be replaced with the second heat dissipation member.

A regenerative braking system includes a capacitor which is electrically connected to a stack and is charged by the stack, a traction motor, a motor control unit which control electric power input to the traction motor and electric power output from the traction motor, a chopper which is connected to the capacitor so as to be ON and OFF switched thereby limiting charging voltage of the capacitor, a braking resistor which consumes regenerative energy so as to serve as an auxiliary brake, and a hybrid control unit which turns on the chopper in case that a charging voltage limit of capacitor is exceeded so as to control overcharge of the capacitor and turns off the chopper in case that charging voltage of the capacitor descends. The capacitor is preferably a super capacitor.
