Its a beefy motor. Its been on robotshop.ca for quite a while. That price is pretty good since you would only need two. I need four of the LM gearhead motors (which are half the cost) but end up being the same cause I need twice as many, where as you only need two of those for the same cost and you have gobs of torque more.
But consider the power, 20 times more powerfull than the lynxmotion GM motors… 20!
and ten times more powerfull than the most powerfull lynxmotion planetary gear motor (that has 14 RPM instead of 300)
But… I think I found the glitch… I guess you can fix it by putting a 20 Amp resistor before that it goes on youre motor controller because the peak current is 42 Amps!
That motor has a 42 amp stall current, and 1421 oz-in of torque.
These are much larger (physically) than any of the motors Lynxmotion sells, so its not surprising they have more torque. But I also bought a Sabertooth 2x25 motor driver to control it (peaks at 50 amps).
mmm, that is still a lot of torque, let’s say I would want to mix it with a servo and create a kinda Superservo (like in the tutorial)… This could be incredibile! (I would like maybe to put it on humanoid arms (the robot would be 1.50 metres and have a wheeled base). Can taht kind of servo hold positions? Is that posible or am I way to far daydreeming?
You can mount the 700 can motors onto the 42mm BaneBot gearboxes as well. The 700 sized motors have twice the power of the 550. Which makes for a very powerful motor.
The real way to do this is to use the motor to drive a linear actuator. Then you don’t have to worry about holding torque. If you convert the linear actuator into a series elastic actuator, you can even make it compliant so you can move it around.

Too bad.
