Ourtunner

For us the Orbit motor series was a completely new development. The Orbit motors are from the out runner principal of brushless motors. Our aim was not just to make a copy, but also to improve it, and we succeeded. The motors are built to the usual excellent Plettenberg quality and are without doubt among the best out runners on the market.

The basic construction principal of an out runner is exactly opposite to the motors we have been building up to now. The wire-wound coils are fixed inside and the metal casing, and the can with the glued on Neodyme-magnets, rotates around the coils.

As usual only the highest-grade materials are used. The metal used for the casings is the same as for the well-proven HP 355 series of motors. The excellent quality and thin gauge help guarantee a high degree of performance and torque. Also in high rpm, for this construction untypical, the motor havs high degrees of effeciency. The coils as usual are wound by hand to a high density. Our magnets are high value neodym made in Germany. After attaching the magnets every casing is balanced on our precision computer controlled machine. This guarantees a perfect rotation of the can. If the can is not able to do this and vibration sets in, due to outside influences, considerable problems will occur. To avoid this the can is supported by a third ball bearing.

The rotating can is now supported on both sides and the third ball baring helps to minimise the air gap between the can and the coils. This makes available high degrees of efficiency and torque. The open rotating can provides excellent cooling, so the motors do not over heat if low throttle is used, and therefore are very efficient.

It is possible to mount the drive on either side of the motor, so please state your preference when ordering. The picture shows the standard version.

These motors are ideally suited for power models, fun fliers, scale models and helicopters.
