Electric and hybrid vehicles will all require an electric motor to provide both motive power and a means of capturing regenerative energy.

Zytek specialise in the design and development of highly salient, 3-phase, internal rotor, permanent magnet, synchronous electric machines for both hybrid and electric vehicles.

Should applications demand an alternative solution, these can be explored through detailed feasibility studies, alternative solutions discussed with customers, and if an alternative topology is agreed as showing advantages over a traditional design, can be manufactured.

We have designed, tested, and manufactured advanced traction and hybrid machines since the mid-1990s, giving an unrivalled level of experience in this field.

Off The Shelf / Semi-Customised / Customised Solutions

We can supply “off the shelf” products, semi-customised solutions where machine length and winding configurations can be employed, and fully custom solutions where ultra-high levels of performance are required or difficult package challenges must be met.

In-House Manufacturing

Our in-house manufacturing facilities enable prototype machine designs to be manufactured by hand, allowing high levels of feedback between our manufacturing and design teams.


Testing and Characterisation

For the testing and characterisation of 3-phase permanent magnet machines and power electronics, we have extensive in-house test facilities.

These comprise five full-size electric machine dynamometers, one with full transient capability and additional low torque spin test facilities.

This ensures that most test activities can be managed in-house, from initial characterisation through to design validation robustness testing.



We have been designing, developing, and converting prototype concept motorsport vehicles since the mid-1990s from our dedicated workshop facilities.

Mechanical Engineering

Our design team includes mechanical engineers with a wide range of skills from product design to vehicle A surface designers with all the necessary skills required for full vehicle build.


We are pioneers in the use of electronics in race and road applications having developed the first digital, re-programmable, microprocessor-controlled engine management system used in Formula 1.


We specialise in the design and development of high performance 3-phase, internal rotor, PMSM electric machines for hybrid and electric vehicles.


Permanent Magnet Synchronous Motor.

Permanent Magnet Synchronous Motors (PMSM) are brushless DC electric motors that use permanent magnets instead of electromagnets for field generation. PMSM motors have no windings in their rotor, so they can be smaller than conventional induction motor designs. They are used in many applications including robotics, automotive, aerospace, industrial automation, consumer electronics, medical devices, power tools, and EV motorsport!

No, we also develop other types of electric machine?

However, for motorsport applications, it is usually required to pursue solutions that offer the highest power and torque density. This will always lead you to the permanent magnet motors solution.

This can be investigated via detailed modelling activities to predict the optimum configuration, but with all things being equal, the inner rotor architecture always gives the best compromise of speed, torque, and power. Should there be a use case where an extreme aspect ratio be required, other topologies may be more beneficial and can be developed

We have been designing, testing, and manufacturing advanced traction and hybrid permanent magnet machines since the mid-1990s.

We designed and developed the original Smart electric drive of which approaching 2,500 units were manufactured.

Yes, these can be designed for extreme aspect ratio designs, or where package limitations mandate a non-round design (as the Smart Crosstown hybrid vehicle).

As machine production volumes increase, our in-house facilities can be utilised to manufacture up to 2,000 units per year.

We will meet and discuss your requirements, and based on that, we will present detailed proposals, which will include all the potential solutions and options. To discuss your project please Contact Us.
