how about dc motor? #12

Open prrraveen opened 8 years ago

prrraveen commented 8 years ago

Stepper motors are costly. One circuit requires 7.5k (2500 motor + 3000 drive + 2000 power supply). They damage fast since they are running on such a high power (48v, 1 Amp). They heat like Iron box.

I have limited knowledge about dc motor. but I think dc motor with quadrature encoder can be cheaper alternate

We have bought 1000rpm ,~6kg torque dc motor along with H bridge. Motor costs 150 rupees and H bridge 50+.
Test these things and lets see if they can be any useful:-

[ ] Acceleration
[ ] speed control
[ ] position control and accuracy
[ ] Easy of programming
[ ] Adding IMU sensor.
[ ] Per unit cost if we plan to use it in Right Arm.
