Transmissions for Electric Vehicles
Our highly customisable transmission solutions for high-performance and specialised electric vehicles are flexible and easy to configure. We offer an off-the-shelf baseline product to support rapid prototype and technology demonstrator development which can be tailored to bespoke specifications for a wide variety of real-world applications in remarkably short lead times.
Off-the-shelf or bespoke solutions available
Designed to offer lightweight, ready to run solutions, these easy to configure units are provided with aluminium casings and are ideal for direct integration into space constrained environments. They couple with the latest range of motors from the major manufacturers and represent an optimum balance of efficiency and performance with low cost of ownership. We offer them stand alone in series supply or as part of our fully integrated EDU packages.
Available to support primary or auxiliary propulsion applications, the ET5-1S Parallel Axis Reduction Drive is a single input – dual output and is designed for flexibility in ratio and configuration of the differential. It is capable of handling up to 500Nm with a maximum input speed of 12,000RPM.
This unit is designed to be highly customisable with a wide range of install orientations, compatible with a range of input motors, available in a choice of ratio options, an optional parking brake, and various options for the lubrication system. These units are ideal for customers requiring a short lead-time for product availability.
