Abstract
A motor controller with a data bit expansion mechanism is provided. The motor controller sets a plurality of pieces of target waveform characteristic data that are used respectively within a plurality of magnetic pole position time intervals to output a motor control output instruction. The motor controller, according to each of the plurality of pieces of target waveform characteristic data, generates a plurality of pieces of sub-target waveform characteristic data in a bit number expansion instruction. The plurality of pieces of sub-target waveform characteristic data are used respectively within a plurality of bit expansion time intervals. The bit number of each of the plurality of pieces of sub-target waveform characteristic data is smaller than an upper limit bit number. The motor controller generates a plurality of bit-expansion waveforms according to the bit number expansion instruction for controlling a motor.
