High Performance Microstepping Driver System based on Five-phase Stepper Motor (sine wave drive)

This paper presents the implementation of microstepping in five – phase hybrid stepper motor. The proposed drive system, in microstepping mode, achieves standard full step angles on five – phase stepper motor in the range of 1, 2, 4, 5, 8, 10, 20, and 40. Low vibration, low noise and improved controllability are achieved using microstepping. A dedicated new lower cost 5 phase pentagon stepping motor controller IC was developed to create a small but powerful package for use in high volume applications. This IC has all the drive functions of a sequencer and can control motor phase currents accurately and efficiently. The step motor driver circuitry consists of four parts as follows: micro-step sequencer, pre-driver and current control, P-channel MOS array and N-channel MOS array. The paper presents the operation of the system in both clockwise and counter clockwise direction at various speeds which is an important need in the field of robotics, automation engineering and textile industries
