Brushless DC-Motors
Brushless DC-motors from FAULHABER stand for maximum performance in the smallest space. They feature the highest values for speed, torque, and service life. They are very low in noise and vibration. They can even handle overload and continuous operation.
- Diameter: 3~44 mm
- Length: 8.4~90 mm
- Nominal voltage: 3~48 V
- Speed up to 100000 min⁻¹
- Torque up to 217 µNm
- Continuous output up to 282 W
The brushless, sensorless DC-Servomotors can be used even in the most challenging applications where space is extremely limited.
The brushless DC-Servomotors are sensorless and available with matching, highly compact gearheads for increasing the output torque, and speed controllers. The brushless DC-Servomotors provide a technology basis that can be modified for projects according to the requirements of the individual customer.
DC-Motors
DC-Motors offers two variants:
Precious metal commutation has low current density and low contact resistance. This variant is particularly well-suited for low-power, battery-powered, and low-start-up voltage applications.
- Diameter: 6 ~ 22 mm
- Length: 15 ~ 32.6 mm
- Nominal voltage: 1.5 ~ 40 V
- Speed up to 24000 min⁻¹
- Torque up to 5.9 mNm
- Continuous output up to 8 W
DC-Micromotors with precious metal commutation
The main benefits of this technology include no cogging torque resulting in smooth positioning and speed control, higher overall efficiency than other DC Motor types, extremely high torque and power in relation to motor size and weight, and a linear relationship between load to speed, current to torque, and voltage to speed. The very low rotor inertia results in superior dynamic characteristics for starting and stopping and the motors exhibit extremely low torque ripple and EMI.
With graphite commutation, the spring-loaded brushes are made of a combination of graphite with copper or silver. They have a large contact surface and achieve a strong contact force for optimal power transmission to the winding, even when shocks or vibrations occur.
- Diameter: 13 ~ 26 mm
- Length: 27.2 ~ 57 mm
- Nominal voltage: 6 ~ 48 V
- Speed up to 10000 min⁻¹
- Torque up to 40 mNm
- Continuous output up to 34 W
DC-Micromotors with graphite commutation
The series combines power, robustness and control in a compact form. The standard drive can be combined with high-resolution optical or magnetic encoders for applications with precise speed control or positioning tasks. A broad and optimally matched selection of gearheads is available to extend the range of requirements that this series is able to fulfil.
