Electrifying performance from small DC servo motors.

This new and highly customised small DC servo motor demonstrates the capability of maxon motor to develop solutions for very difficult requirements.

There are maxon motors everywhere around you, in your car, home appliances, taking care of your money, drilling for oil and even exploring Mars. It’s the last examples here that show how small DC servo motors are becoming more and more specialised. The latest in the list of specialist motor applications is the world’s un-quenching thirst for electricity. The constant demand for more power results in continual power network upgrades. However installing more cables on a 500kV line without interrupting supply is not so easy – unless you get a robot to do it. Building the robot then becomes the challenge and the DC servo motor requirements were not trivial either… “We are looking for a small lightweight DC servo motor solution with 50rpm and 15Nm of torque.” At this point the sales engineer thought “ok, easy so far” But then comes the “Oh and also, in the event of an emergency or system malfunction we need to disengage the motor and gearhead with a clutch mechanism, so we also need a shaft that is 145mm long and the motor and gearbox can only be around 100mm long. We would also need a specific connector and a specific cable length. Oh yes I almost forgot, we need it to operate in an extra high voltage environment.” But maxon motor thrives on meeting tough requirements. Solution: maxon brushless DC flat servo motor, the EC 45 Flat 70W 24Vdc fitted with a custom 150mm ribbon cable, custom connector fitted to a 42mm Ceramic Planetary Gearhead with a ratio of 126:1 featuring a custom machined 145mm output shaft, custom machined final stage planet carrier and planet pins, ISO 2491-A4x4x20 key size, machined keyway Located 14mm from shaft end. …Easy if you say it fast. It is not only ground-breaking in terms of customisations but it is also an example of extreme power density. Maxon motor was able to deliver this exceptional servo motor unit with its associated motor controller for under $1000 dollars in 8 weeks.
