Synchronous electric motors |
|
 Our main research and development effort is focused on the field of synchronous electric machines, especially brushless permanent magnet motors for direct drive applications. The result of many years of development is a novel SDG construction of synchronous multiphase electric machines. Advantages of the SDG construction include higher torque density and improved thermal issues compared to standard constructions. Some of these issues are demonstrated by Electrodrive high performance synchronous electric motors and generators based on the SDG construction.

Electrodrive is a family of brushless permanent magnet synchronous electric motors and generators. Their design is based on our proprietary SDG construction and has been optimized for use in direct drive of electric driven vehicles. The following table shows some obtainable motor characteristics for different motor dimensions. | Type | Torque
[Nm] | Peak torque
[Nm] | Speed
[min-1] | Max speed
[min-1] | Diameter
[mm] | Length

[kg] | P03 28M180D
| 28 | 120 | 750 | 2600 | 180 | 50 | 4,4 | P03 70M252D-F
| 70 | 300 | 600 | 2000 | 252 | 62 | 8,2 | P03 320M360D-F
| 320 | 1300 | 400 | 1300 | 360 | 110 | 25,0 |
 Electrodrive motors are usually designed as hub motors. They utilize a compact and durable casing able to support full mass of a vehicle, with bearings capable of withstanding high radial and axial loads. Casing can include integrated channels for a cooling medium. Standard wheel rims can easily be mounted to a motor. A brief introductory document is also available for download  .
