With the advent of powerful controlling electronics the design of brushless motors was made possible. With this technology we were able to go in new directions.

Through intense basic research we have gained the necessary knowledge to work future orientated in order to constantly improve and adapt our motors to a higher level. New geometries are used on our brushless motors to considerably improve the power to weight ratio and to reduce the amount of wear on moving parts to a minimum. Our motors are power drives constructed to the new inside-out principle.

This means the rotor at the centre contains neodyme-magnets and iron, not wire coils as before. The construction of a normal brushed motor therefore being turned around giving the possibility to use high performance materials and new technology. We have developed new highly efficient materials for the stator orientated towards extremely high levels of performance. With this newly shaped stator we have the unique possibility to build motors of 4 to 10 poles. The amount of iron in the stator is thus reduced and with it the weight. The motors are multi pole with the rotors being made of a weight saving tubular construction hence the motor gains more dynamics as opposed to solid magnate technology. This multipole technology results in much higher torque.

To get quiet vibration free running, all the rotors are precision balanced on a computer-aided machine. The stators are hand wound giving guaranteed high grade precision windings.

Our gearboxes are equipped with planet type gears with ball and needle bearings giving a friction free run and long life. The gearboxes are 97% efficient; these low mechanical losses can be compensated for by the use of large propellers.

The gearboxes as well as the motors are fully tested under gruelling competition-conditions. For the multipolemotors it is necessary to a controller that can manage a multi-pole motor and the high revolutions involved. (see motor/controller page).

Our target is to offer high torque motors for direct and geared applications. We have been successful in designing and constructing low weight brushless motors with extremely high torque levels for direct drives and serial produce them. We can also offer slim, low weight motors with integrated planet gearboxes suitable for high revolutions and long life.
