Description
A large torque flywheel control circuit for satellites Technical field [0001] The present invention relates to satellite technology, in particular to a large torque flywheel control circuit for satellites. Background technique In traditional satellite flywheel, working voltage is generally 28V, and output torque is relatively small, and maximum is 0.2N.m, in During the operation of the flywheel, the linearity of the flywheel torque and speed output can be better guaranteed. For high torque flywheels, the output torque is 0.35N.m, because it works in the state of high voltage (up to 60V) and high current, with the increase of flywheel speed, once The interference between the ground and the secondary ground, the influence of the back electromotive force and the increase of the friction force are getting bigger and bigger, and it is impossible to guarantee the full rotation of the high-torque flywheel The linearity of torque and speed output within the speed range. In a...
