Green MotorSport EV Motors
THE GMS M1 Project
Water-Cooled / Liquid cooled Motors
We offer bespoke motors and complete systems. With a unique blend of performance attributes - high efficiency, robustness, reliability, high temperature capability and operation over wide speed ranges. Our range of electric motors have been specifically designed to meet the demands of high powered drive trains for EV application. We offer a compact solution, high torque capability for large or small motors. Motors used in electric and hybrid vehicles have very different demands from those used in an industrial application. The power to weight ratio should be as high as possible, requiring the chosen motor to be compact and light.
The reliability and durability of our electric motors is a direct result of the use of top quality materials, stringent quality control and an experienced design team. We specialize in the development and production of power dense, high efficiency, high performance AC electric motors.
It is important that a motor uses the available energy efficiently, ensuring maximum performance from the electrical energy source.

The New GMS High performance AC Liquid cooled motor
The project motor unit, called the GMS M1 boasts incredible performance characteristics and amazing value! The AC water cooled 48 volt high performance, high frequency motor is capable of pulling 650 amps peak. The new motor delivers its power in a very different way from the conventional DC motor, being comparable to our former 40 kW DC motor used in our older performance kart which set speed records at Rockingham race track in the UK. The performance is obtained by an impressive water cooling system and efficient windings. The motorís cooling system is unique and is the first of itís kind whereby the water cooling jacket is totally seamless. The new water cooled motor is designed for high performance and has been engineered to the highest quality in the UK. The M1 motor design is compact due to itís liquid cooling, highly efficient windings and the benefits of being brushless and totally sealed from the elements making it durable and robust. This makes it suitable for almost any application, from electric cars to water craft or any other high performance application where keeping costs low is of importance. The technology will be proven in motorsport, the most demanding environment known for its automotive research and development. The AC motor is a joint effort of Green MotorSport technology partners, with over 40 yearsí combined expertise in the electric motor business.
The new 48v liquid cooled GMS M1 AC electric motor is ideal for a range of heavy duty applications. Electric cars, boats & electric motorcycles. Its weight is 15.543 KG without coolant. (Motor unit contains 1 litre of coolant within its jacket at all times) ( MAX RPM 8000) motor requires continuous coolant circulation. The motor is now under rigorous testing in our super kart.

Computer adjustments for fine tuning performance of operating profile for best efficiency. (EMP locked down performance tweaking with each unit to avoid manufacturing inaccuracies.)
Each motor must be used with a certified performance profile. The unique designed EMP embedded controller software.
Mass Production Motors
Currently we are now in the position to offer you the refined mass produced version of the M1 liquid cooled electric motor. The Green MotorSport powertrains manufacturing team have made a number of changes to the M1 in order to significantly reduce the retail price of the motor. As you can see from our new M1 motor drawings below, we have changed the shape of the cooling jacket and the cooling inlets as well as the main power supply connection fittings. With all these fine tunings and enhanced structural durability changes, we have shaved even more weight off the M1 motor. The weight of the unit is now 15.543 KG.
