Current Platforms Derivatives

We currently have a range of interior permanent magnet (IPM) and surface-mounted permanent magnet (SPM) platforms and can provide a solution rapidly, with minimum non-recurring engineering (NRE) if your requirements can be met by one of these. Using a simple application template to understand your system performance and constraints we can adjust length, windings and other aspects of our core technology package to give you the best performing motor.

Electric Propulsion Systems

Maximising performance and efficiency with minimal space

Electric Propulsion Systems (EPS) are becoming an increasingly attractive option for manufacturers of passenger cars, small commercial vehicles, race cars and motorcycles where hybrid and all-electric powertrains are being developed.

These all-in-one electric propulsion systems combine transmissions (single or multi-speed), electric motors and inverter technology which have been optimised for high efficiency and volume manufacture.

Working with OEM’s and Tier 1 suppliers Integral e-Drive are able to integrate its own market leading electric motors and inverters with 3rd party transmissions to deliver low weight, compact and highly efficient systems for primary and secondary propulsion for pure electric and hybrid transportation.

Whilst the EPS’s developed utilise our own motors and inverters, we are equally adept to integrate 3rd party inverters should the client choose.

Furthermore, all Electric Propulsion Systems carry the same DNA philosophy as our motors and inverters and are specifically designed to be class leading in power and torque density. They leverage on Integral Powertrain’s Intellectual Property in design and manufacture utilising our patented cooling and electromagnetic technology.

All EPS’s have been designed for simple integration either at the front or rear axle of passenger cars, light commercial vehicles and in race cars.

Drawing upon our rule based design method the Propulsion Systems are designed to be scalable for power and torque vs available space alongside incorporating options for various gear ratios (to scale the torque), electronically controlled park-lock systems and torque vectoring as required.

Key features:

  • Compact design – easy to install
  • Lightweight – highest power to weight ratio
  • Proven electric motor and inverter technology
  • Integrated common cooling system with advanced thermal management
  • Optimised inverter software and safety features
  • Single or multi-speed transmission options
  • Flexible manufacturing concept
  • High efficiency >98% – meaning reduced energy storage requirements
  • 200 – 1000kW – high performance scalability allows for a broad spectrum of applications for various applications
  • Water/Glycol cooled as standard – reducing on-board cooling complexities

Products fall into three categories:

  • Motor and inverter integrated EDU
  • Motor and transmission integrated EDU
  • Fully integrated motor, inverter & transmission EPS

Integral e-Drive Core Technology Bespoke electric motors and inverters

Core Technology, Bespoke Motor (CTB)

A true differentiator of our business is the capability to configure our core e-Drive technology to meet your precise performance and package requirements. Once we have completed a simple application template we can use our in-house tools to outline a range of possible solutions and, working together with you, select the best match. Using an advanced, rule based design system Integral e-Drive can then rapidly design and procure optimised motors which automatically draw upon our proven expertise and experience.

Control Electronics and Software

Complementing our world class in-house inverter technology, Integral e-Drive also has a track record of working with other inverter providers according to technical and commercial requirements.

Our base software is Autosar compliant and has been developed in line with rigorous automotive standards running either on micro controller NXP SPC5744P, or where higher processing speed is required, a combination of this and FPGA from Xilinx.

Our application software contains all that is needed to drive SPM and IPM machines with precision and efficiency including speed and torque controllers, thermal models and system diagnostics. By using a model-based approach and established MiL / SiL / HiL validation processes we can also configure to meet specialist requirements when applicable.

Special Projects

Whilst the vast majority of applications can be met with our core technology bespoke (CTB) motors, there are applications so specific in their requirements or integration concepts that they need new core technologies for some of the sub-systems. This could for example be a motor designed to operate at the bottom of the sea or in a nuclear reactor cooled by liquid sodium. As genuine, first-principles engineers with a track record of meeting the most demanding briefs, Integral e-Drive are very well placed to meet your needs, however extreme.

Core Technology R&D

In 10 years of e-Drive innovation we have achieved genuine technology leadership in high power density motors and also cost economic low voltage drives; as a company led by engineers, we are passionate about maintaining this position.

We have a substantial on-going R&D program to evaluate new technology and to provide year-on-year improvements. All R&D activities at Integral e-Drive are managed through a series of gateways so that the most promising continue on a path that will allow them to be incorporated into our core technology and future products.

Current work-streams include:

  • Advanced bearing systems
  • Increased magnet retention system capacity
  • A new winding concept for AC loss reduction and increased partial discharge resistance
  • Use of advanced materials to improve cooling
  • AC to AC inverter architectures

Our Focus is our Clients’ Success

Innovative & Pioneering
