This Design Idea further develops a previous one integrating a stepper-motor driver in a CPLD (Reference 1). However, this idea integrates not only the driver, but also a simple one-axis stepper-motor ...

For maximum efficiency, the boundary conditions of the complete electro-mechanical system should be mapped During the optimization of a stepper-motor-based motion control system design an engineer ...

The schematic of a PMSM drive using a DTC-based speed loop PDFF controller is shown in Fig. 1. This DTC scheme is implemented in stator flux frame, which requires knowledge of stator flux in ...

The SMC-32 stepping motor controller/driver can control four-, six-, or eight-lead, two/four-phase stepping motors with currents up to 3 A per phase. Measuring only 4 by 3.75 by 1.5 in., the unit ...

Extending the company’s bipolar stepper motor control family are two SPI versions of a motor driver capable of peak currents up to 800 mA and suitable for use with an external microcontroller. The ...

Stepper motors resemble servo motors in that both types are characterized by an ability to rotate a partial turn and then stop for any interval with or without holding torque. In addition, both motor ...
