COMPACT 850 30 V Graupner 6525 GRAUPNER COMPACT BRUSHLESS motors.
New high-performance BRUSHLESS motors, expanding the existing range. The impressive feature of the motors in this series is their enormously high torque, and in direct-drive applications they show their full performance potential. The new GRAUPNER COMPACT motors are brushless “outrunners”, i.e. the outer motor case rotates, and drives the motor shaft. This design principle results in ultra-compact electric motors which produce an outstanding performance without the need for a gearbox. A further advantage: GRAUPNER COMPACT motors are very light in weight compared to conventional motors of comparable performance.
