摘要： Disclosed is an electric-bicycle driving apparatus. The electric-bicycle driving apparatus includes a speed-change mode operator to output a low-speed or high-speed mode signal, a controller to receive the low-speed or high-speed mode signal from the speed-change mode operator and to output a first or second control-signal corresponding to the low-speed or high-speed mode signal, a generation-signal provider to provide a generation-signal output from a generator, and a motor-driver operating-signal regulator to receive the first or second control signal when the speed-change mode operator outputs the low-speed or high-speed mode signal, to regulate a level of the generation-signal output from the generation-signal provider and to provide the resulting signal to a motor driver that drives a motor, the motor-driver operating-signal regulator providing a lowered level of generation-signal to the motor driver that is operated upon receiving power of a battery, and cutting off an abnormal signal from the motor driver.

摘要： A current reference generator to control a brushless motor in a motor control system is provided. The current reference generator includes a locate peak torque module that determines a maximum possible torque and a direct axis current that corresponds to the maximum possible torque based on motor parameters, a maximum voltage, a motor velocity of the brushless motor, and a sign of a torque command. A limit torque command module limits the torque command to the maximum possible torque. A locate minimum current module determines a value of the direct axis current that results in a minimum motor current. A solve current reference module generates a reference vector that satisfies the torque command as limited by the direct axis current that corresponds to the maximum possible torque and the direct axis current that results in the minimum motor current.

摘要： A sensorless motor controller (22) includes a variable link control, including a radiation-hardened field programmable gate array (FPGA) (28) and a back electromotive force (EMF) decoder circuit (30). The back EMF decoder (30) infers the position of a rotor of the motor (24). A filter (38) on the decoder (30) conditions the back EMF signal and has multiple cutoff frequencies which can be dynamically controlled by the FPGA (28) in order to compensate for phase shift in the back EMF signal. The FPGA (28) also controls a variable DC link and its digital speed control loop.

摘要： Provided are a motor control apparatus and method. The motor control apparatus includes a power supply unit supplying power to a motor, a power device selectively blocking current supplied into the motor according to whether the current supplied from the power supply unit to the motor is above a reference current value, a control unit controlling an intensity of the current supplied from the power supply unit into the motor, and a load torque detection unit detecting a load torque generated in the motor when the motor is rotated. The control unit controls a maximum value of the current to be supplied into the motor so that the maximum value is less than the reference current value when the maximum value of the load torque detected by the load torque detection unit is above a maximum motor output due to the reference current value.
