The G48-series represent the latest design in compact
Additional Features
AC Controllers. These reliable controllers are intended
xxAdvanced flux vector control
for on-road and off-road electric vehicles and feature the
smallest size in the industry for their power capacity.
Thanks to the high efficiency it is possible to integrate
these controllers into very tight spaces without sacrificing
performance. The design has been optimized for the
lowest possible installed cost while maintaining superior
reliability in the most demanding applications.
Choice of Motors Types
Gen4 controllers are designed to control both AC Asynchronous
and Permanent Magnet Synchronous motors. This feature allow
users to select an optimal motor type for the application.
Multiple Sensor Feedback Possibilities
Hardware inputs and software control for UVW, Pulse Encoder
and Sin/Cos Feedback Devices are provided for flexibility.
Fully CANopen Compliant
A CANopen bus allows easy interconnection of controllers
and devices such as displays and driver controls. The CAN bus
allows the user to wire the vehicle to best suit vehicle layout
since inputs and outputs can be connected to any of the
controllers on the vehicle and the desired status is passed over
the CAN network to the relevant motor controller.
Excessive Battery Discharge Protection
Allowed peak battery current is not always fixed and can vary
with battery conditions such as temperature and state of
discharge. The Gen4 controllers can dynamically change the
allowed battery current by exchanging CAN messages with a
compatible Battery Management System. This feature assists in
optimizing driving range and improving the battery life.

Self-characterization
General Specifications
Sevcons unique Self Characterization enables a Gen4 controller
to automatically define and optimize parameters for Induction
AC motors. This feature provides quick set-up and allows
customers to select motor suppliers of their choice without
worrying about compatibility between controller and motor.
