Yaskawa, the Japanese motor drive and PV inverter manufacturer has added a new servo motor to its catalog. This servo motor, called “Σ-7 F”, is based on Gallium Nitride devices produced by Transphorm. It’s not the first time that Yaskawa announce a power electronics converter using Transphorm GaN transistors. A PV inverter was released in 2015. It was already using Transphorm’s devices.
The Σ-7 F series servo motor are three-phase bridge topology based, using high-voltage Gallium Nitride devices in TO-220 packages. The 100W to 400W servo motor product line will progressively include a GaN option, allowing a reduction in size.
