Actro motors combine most modern drive technology and best robustness properties. This combination makes Actro motors the ideal ones for rough modeling applications.
The following properties characterize Actro motors:
**Brushless, sensor less commutated synchron motor**
**Outside rotation motor of high torque for direct drive applications**
**Very low maintenance, nearly wear less, because free of mechanical collector and gear boxes**
**High efficiency and polished construction lead to best thermal and mechanical robustness**
Construction of ACTRO motors:
Due to the outside rotation principle and the 8 magnet pole design enormous torque and low weight are achieved. The open designed form of the rotating case ensure an excellent air cooling of the complete motor. The results are best persistence properties also on high performance. The remarkable compact form of the motors and the robust designed double bearing supported rotor offers a very smooth run.
The heli range of Actro 24 motors can be installed in the model just like conventional designs, i.e. the power plant is simply attached from the front using two of four M3 screws. The motor cables exit the motor at right-angles to the motor shaft; an arrangement which offers advantages in many model helicopters.
This new design allows you to save about 30 – 40 g compared to normal Actro motors when you consider that an additional hub is not required. The motors feature 5 mm and 8 mm shaft steps; internally the shaft is of 6 mm diameter, and runs in heavy-duty ball bearings designed to absorb the gearbox forces encountered in modern helicopters and 8 mm high-performance machines. Actro heli motors are available with 3, 4 and 5 winds.
