The brushless DC servo motor 1645 ... BHS from Faulhaber offers extremely short response time, high RPM, and large radial load. It extends the BHx series with 16 mm diameter to an even more compact version, which is only 45 mm long. In addition, this extremely powerful BLDC motor causes little vibration and heat generation. This makes it suitable for applications with high power requirements and tight installation spaces.
The BHx series consists of gapless, brushless high-performance motors in two-pole technology. The 1645 ... BHS version with 100.000 min-1 achieves a significantly higher speed than the motors of this size available on the market so far. It also peaks at maximum radial load (18 N), power density (58,5 W) and torque (8 mNm). With a suitable planetary gearbox, the engine can deliver a very high torque of 12.000 mNm even with 1 min-800.
An efficiency of 90% makes the engine very energy-efficient. It achieves its extremely short response time thanks to extremely low mechanical start-up time constant and rotor inertia values as well as very fast angular acceleration. Together with the flat slope of the n / m characteristic (429 min-1 / mNm), this results in an optimal running behavior of the motor, which follows fluctuating power requirements without delay.
Digital Hall sensors are integrated, an integrated incremental encoder is possible as a special version. A wide range of connection components such as speed and motion controller, control, gearbox are available for different types of applications. Typical fields of application are, for example, electric grippers, small handpieces, robotic systems, laboratory automation or mechatronic instruments of all kinds.
