FAULHABER’s 1645 ... BHS brushless DC servomotor features a short response time, high speed and large permissible radial load. It is a more compact version of the BHx series, measuring 45 mm long. The powerful BLDC motor is also characterised by low vibration and heat development.

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 1645 … BHS version is claimed to reach a higher speed than similar-size motors on the market. It also features high 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 high torque of 800 nNm at 12,000 rpm.

At 90% efficiency and with minimal heat development and vibration, the motor is energy efficient. Its short response time is due to low mechanical start time constant and rotor inertia values as well as its fast angular acceleration. In conjunction with the flat slope of the n/M characteristic curve (429 rpm/mNm), this yields the motor’s optimal running behaviour, which is thus capable of keeping up with fluctuating output requirements with no delay.

Digital Hall sensors are built in. An integrated incremental sensor is optionally available. A wide range of connecting components is available for different applications, from speed and motion controller through to control and gearhead.

The motor’s rugged, compact design and good performance data make it particularly suitable for demanding applications that offer little space. Typical uses are electric grippers, small handpieces, robotic systems, lab automation and mechatronic instruments of all types.
