Controllers

YASA Controllers

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.
