20130147403 | Electro-Mechanical Drive with Extended Constant Power Speed Range - Embodiments of the invention comprise a multi-input range box driven by multiple electric drives. Range shifting involves momentarily increasing the current through all but a given motor, to a level that will carry the entire load, comprising specified constant power. Simultaneously, torque of the given motor is reduced to zero. The given motor is then disconnected from supplying power, is synchronized to the input speed of the new speed range, and is then engaged for the new range. The above sequence is then repeated for each remaining motors, in turn. The motor current is re-equalized for all of the motors, after all the motors have been connected to provide power at the new range. Thus, there is no interruption in power flow during a range shift, and the motors are always used to deliver power, rather than to serve as a brake. | 06-13-2013 |
