The powerful 1645... BHS


The powerful 1645... BHS The 1645... BHS brushless DC servomotor from FAULHABER is setting the bar in its class with an extremely short response time, high speed and large permissible radial load.

The successful BHx series with a diameter of 16 mm is thus further expanded by an even more compact version which is only 45 mm long. And much like the rest of the product range, this extremely powerful BLDC motor is also characterised by low vibration and heat development. It is therefore predestined for applications that demand a lot of power and offer little space. 

The BHx series consists of gapless, brushless high-performance motors with 2-pole technology and a diameter of 16 mm. At 100 000 rpm, the new 1645 … BHS version reaches a significantly higher speed compared to similar-size motors on the market. It also achieves top values at maximum radial load (18 N), power density (58.5 W) and torque (8 mNm). In combination with a suitable planetary gearhead, the motor is capable of delivering a very high torque of 800 nNm at just 12 000 rpm.

The "big brother" of the 1645 … BHS – namely the 1660 … BHS and BHT series – can be used if more installation space is available. These also offer top performance data in their size class. The two versions are optimised for high speed (BHS) and high torque (BHT).
