The process of linear motor commutation is not well understood and is often glossed over, but it has a significant effect on performance. Motor force (torque in a rotary motor) is proportional to the magnitudes of the magnetic fields of the magnet track (stator in a rotary motor) and forcer (rotor in a rotary motor), multiplied […]

Inertia Matching: Why Perfect Isn’t Always Best
Inertia matching is one of the inexact sciences of motion system design. When a motor and a load are coupled together, the ratio of load inertia to motor inertia determines how well the motor can control the load during acceleration and deceleration. In theory, a “perfect” inertia match of 1:1 (load inertia equals motor inertia) should […]
