How important is mechanical alignment for optimal motor performance?
For ironless motor, it’s not important at all. Trilogy Ironless motors are completely unaffected by misalignment provided the motor coil is not rubbing on the magnet track. We have provided a generous clearance between coil and track, so all you have to do is bolt it down and go. No tweaking is required. This also means that if a coil ever fails, then it can be quickly replaced without regard for any realignment procedures, shims etc. Ironcore motors require that the air gap be maintained at about 0.8-1.0mm. A slightly lesser or greater gap will change the force constant of the motor. The gap tolerance for Slotless motor is also 1mm but is more tolerant of variation than the Ironcore motors. • Do similar motors have identical performance characteristics? Yes and No. The coils are identical having exactly the same number of turns. The magnet tracks can see a variation in magnet strengths of 3-5% from one manufactured lot to the next. All magnets will meet the minimal magnet specificatio
