The new I/O module controls stepper motors with Modbus/TCP, Ethernet/IP or PROFINET interface to host PC, PLC or PAC.

Conventional modular multilevel converter (MMC) has severe limitation to operate at low frequency for the application of variable-speed induction motor drive. Fluctuation of submodule (SM) capacitor ...

This paper proposes a nonlinear sliding-mode speed-control scheme for interior permanent-magnet synchronous motor (IPMSM) drives incorporating the maximum-torque-per-ampere trajectory. The drive uses ...
