YASA’s controller series provides powertrain designers with new ways to optimise hybrid and electric vehicle performance, range and cost. The controllers achieve industry leading peak power density of > 40 kVA / L.
The controllers are suitable for use with induction and permanent-magnet machines and, when coupled with YASA axial-flux electric motors, the controllers offer best-in-class size, weight, efficiency and control dynamics.
YASA Si400 Motor controller
The YASA Si400 controller is the first in the series and is available to OEM customers and tier-one partners.
The Si400 delivers up to 200kVA from a 5 litre package weighing just 5.75kg. The controller features innovative thermal management including dielectric oil cooling and is suitable for use with induction, permanent magnet and axial-flux electric motors.
When coupled with YASA’s axial-flux electric motors, the Si400 controller offers best-in-class efficiency and control dynamics.
