Hextronic DT700 as a stepper motor


Hobbyking 18A driving Hextronic DT700 as a stepper (1 min 25 sec)



It turned out just enough of the ancient DT700's were acquired over the years to make exactly 8 legs. 1 would have to be rewound & the exact number of turns is unknown. It seemed to be 19 turns in a delta. The ESC department has 5 Hobbyking 35A's, 1 Hobbyking 18A, 1 Castle creation 35A, 1 Align 35A. The last 2 are based on the 8051, so quite hard to reprogram.

They're amazingly still sold. They performed much better than the smaller motors. They could jump the load with only 12V. With active cooling, encoder feedback, reducing the lever size, they could probably just manage a slow bounding movement.

Active cooling has been deemed essential for any application. Even with active cooling, overheating still makes it impossible for them to hold the torque longer than a second. The mane problem with continuing is finding encoders for feedback.
