Maxon Motors releases small DC servomotor for high vibration and high reliability requirements

Maxon Motor Australia announces the release of a new range of small DC servomotors specifically designed for the high vibration and high reliability requirements of aircraft applications.

The scaled design of the new DC servomotor, gearbox and encoder combination makes it particularly suitable for aviation applications. Any high torque DC motor requirement is addressed by beginning at the load and working backwards with the shaft, gearing, motor, encoder and the control method to create a servo gearmotor that fits the application.

Maxon Motors’ latest range of DC motors, the DCX, allows the design engineer to individually configure the components the same way. In the context of an aviation application, especially within a propeller or engine bay, the motor is exposed to high vibration that requires a significantly robust shaft and bearing system. But the strength of the drive system often comes at the expense of the servo gear motor’s mass.

With the new DCX configuration the gearhead shaft and bearing are optimised for high torque and vibration requirements at the output stage, while the input stage is stepped down in diameter as it only has to transmit lower torque levels, thereby, reducing the mass. Similarly the encoder is smaller at only 10mm in diameter and weighs less than 5 grams, producing the most torque possible from the lightest motor system possible.

More reliability is achieved with laser welding used throughout the assembly process, at the bearing system, between the gearhead stages and even to assemble the motor and gearhead together.
