This migth be a bit of an odd question... I got two brushless motors from an old air-board.

They are 350 W each and I'm thinking of mounting them together for better torque. But what would happen? If I mount them too close will they interfere with each other?

This is a picture off how i was thinking adding them together: enter image description here

  • \$\begingroup\$ It's brushless. Not having brushes. Coupling two motors for a single axis is a non-trivial mechanical challenge (that's it - not EE). \$\endgroup\$ – Eugene Sh. May 31 at 17:21
  • \$\begingroup\$ Magnetic crosstalk is an unknown with only this picture but mainly an EMI issue. \$\endgroup\$ – Sunnyskyguy EE75 May 31 at 17:57
  • \$\begingroup\$ Just don't try to drive both motors with the same drive because brushless drives need to know the exact rotor position which means a single drive can't commutate two motors unless both motors are mechanically locked to each other in proper alignment. \$\endgroup\$ – DKNguyen May 31 at 18:04
  • \$\begingroup\$ I will be using two drive-controllers for the motors so that will not be a problem. Its just that i wonder if the magnetict felt from the two motors will cause any problems, and lose a bit of performance \$\endgroup\$ – Simon Watti May 31 at 18:14

    \$\begingroup\$ Cross coupling between motors will not cause motor problems. There is a SMALL possibility that induced voltages will cause problems to the other controller's ability to sense motor position BUT very unlikely \$\endgroup\$ – Russell McMahon May 31 at 19:08
