COMPACT 235 9,6 V Graupner 7705 GRAUPNER COMPACT BRUSHLESS motors.
A range of high-performance BRUSHLESS motors. The impressive feature of this series of power plants is their enormously high torque, and it is in direct-drive applications that they show their full power potential. GRAUPNER COMPACT motors are brushless external-rotor (out-runner) types, i.e. the outer motor jacket rotates and drives the motor shaft. This design principle resultsin ultra-compact electric motors capable of an outstanding performance without recourse to a gearbox. An additional advantage: the weight of GRAUPNER COMPACT motors is very low compared to that of conventional motors.
Ultra-light GRAUPNER COMPACT motors with weights below 45 g, i.e. less than a SPEED 300 electric motor, and therefore an excellent choice for lightweight Depron or Styrofoam models. The preferred energy source is a 2-cell or 3-cell Li-Po pack.
