As part of its mission to make world-class electric drives accessible, a British electric motor manufacturer Integral e-Drive has announced the launch of a family of three ultra-high-performance machines off-the-shelf in single sample quantities.

Produced in the new Milton Keynes facility according to automotive industry standards, the CTSM242 motors are based on Core Technology, a particular architecture that combines a meticulous design of the electromagnetic part with a thermal management system that cools both the stator and the rotor. The e-motor is compact, lightweight, and power-dense for use in high-performance traction, propulsion, power generation, and other specialist high-power demanding applications.

The CTSM242 motor combines up to 400kW and 520Nm in a compact package with a mass of less than 30 kg and a maximum speed of 15,000 revs/min making it the highest performing off-the-shelf machine by some margin. These are values that guarantee a peak power of over 12.5 kW/kg.

These engines are not an absolute novelty: they have already collected numerous appreciations in premium racing and hypercar markets, sectors in which they have found application until now. Following investments in in-house manufacturing processes, it has now made this technology accessible to higher volume applications.

The CTSM242 can be combined with third-party inverters, but it offers unparalleled efficiency and control dynamics when coupled with Integral Powertrain’s SiC high-performance inverter (MCU). These engines boast an efficiency close to 97%, something unattainable for an internal combustion engine.

The CTSM 242 is enabling clients to access world-class power density and efficiency manufactured to automotive quality standards from our new production facility,said Andy Cross, Chief Technical Officer. “Our scalable core technology platforms enable us to match precisely our clients’ requirements, but for some, it is important to get up and to run quickly and at minimum cost before any optimization phase. In these cases, this standard ‘off-the-shelf product is extremely attractive.”

This new range of electric motors is ready to go into production, which Integral Powertrain will manage internally in a new plant.
