One concern I have is the heat rise when the bldc armature is under high torque at 0 rpm. The 1500 Hp ac drilling motors used on many drilling rigs require external fans to cool the motors as they lower heavy loads at near zero rpm.
Hola, estaba viendo tus videos y queria hacer un proyecto de robotica, pero necesito un controlador pa los motores Brushless, hay varios en el mercado pero los veo caros, entonces no se si me equivoque y me gaste el dinero, sabria decirme que controlador necesito para unos motores de Hoverboard Blushless?
If the actuator knows what position it is at, it should be able to make a smarter move when going to a set position. Rather than going more than 1/2 rotation to get to a position, the actuator should be able to make a shorter move in the other direction to get where it needs to be.
You need to mechanically align or somehow set an offset that can be added or subtracted from the position to make sure it always goes to the right spot.
Thanks. Torque is definitely the big issue. I don't want to go bigger than what I already have so my next version will use a servo which has about the same amount of torque but a fraction of the weight/size.

Would using actual metal bearings help make it quieter?

Have a look at James Bruton's videos. He has quite some experience with cycloidal drives.
Yeah I'm a long time follower of his channel. His cycloidal drive actuators are very well done.
Great design! Maybe slightly bigger version of it with higher torque motor and higher gear ratio can be very capable! Thank you for sharing!

cool job respectful

Nice
