Method for voltage feedback for current mode linear motor driver |
摘要 |
Methods and systems for driving a motor are disclosed. A center tap voltage and a desired center tap voltage are used to generate a voltage feedback. A power amplifier receives a reference current and the voltage feedback. The power amplifier provides a phase current to a phase of a motor. The phase current is substantially centered about the desired center tap voltage as a consequence of the voltage feedback. Thus, high-side to low-side or state to state current variations are reduced thereby reducing the occurrence of problems such as torque ripple and back EMF.
