HighVoltage Brushless Servo (HBS)

HBS (HighVoltage-Brushless-Servo) combines the bundled performance of brushless technology with all the advantages of high-voltage servos. In addition to incomparable acceleration behavior, higher efficiency and no wear and tear on carbon brushes, these servos can be supplied with an operating voltage of up to 8.4V. A direct connection of 2-cell LiPo batteries is now possible without any problems, and these servos also provide high performance with an operating voltage of only 6V. The precision in production and assembly as well as the highest component quality provide the servo output with unconditional power and speed. A new dimension in the combination of force, speed, acceleration, positioning accuracy and resolution.
