Nidec SR Drives Ltd has worked with a major automotive
component supplier to respond to a growing need for technology
which reduces fuel consumption and emissions while preserving
as much of the existing vehicle infrastructure as possible. The
result is a 12V, belt-driven starter-generator which allows “Stop-Go” operation
of motor vehicles.
The starter-generator will
deliver up to 65Nm cranking torque, 2.4kW cranking power and
3kW generated power. The latest
technology developments and manufacturing techniques have been
employed to maximize the continuous output of the generator using
liquid cooling from the engine coolant circuit.
Position sensorless control coupled with state-of-the-art
MOSFET technology leads to a cost-effective solution with a 7:1
constant power region and high generating efficiency across the
speed and load range.
