Electric Motors - Introduction

At Gravitron we have years of experience and expertise in the field of electric motor design. We have evolved with advancements in technology and refined our design approach.

The majority of the electric motors that we now develop are of the AC induction type. We have moved to this type in preference to the traditional DC brushed electric motors as the benefits are significant.

Not having brushes means that the AC brushless electric motors experience minimal internal wear & tear and can therefore be designed with a sealed water-tight casing. This makes them very robust with low maintenance. Brushless electric motors are lighter weight than a brushed equivalent, they have good efficiency and are extremely cost-effective. Our recent developments have taken two main paths: air-cooled & water-cooled.

If you are planning a project which requires an electric motor we will assess your requirements and suggest a suitable motor or, alternatively, we can design a custom electric motor especially for your needs.

We can supply all our motors with an appropriate variable speed controller and the energy source of your choice (i.e. battery or an alternative).

Brushless AC Traction Motors

We can produce brushless motors with a range of specifications, below are our typical brushless motor design power output values.

  Air-Cooled - 5kw & 10kw
  Water-Cooled - 10kw & 20kw

Custom Electric Motors

Some of our previous motor projects: These motors were designed to specific requirements and may give you an insight into the range of applications we can design for.
