The basic design of the ThinGap Embedded Motor makes far, far smoother motion possible than with any other motor we know of. Measured torque ripple is 102 lower than any other published data which allows for use in applications requiring smooth fluid motion.
Magnetic Forces Are Limited
- Beyond “zero cogging” due to no eddy currents and no hysteresis.
- No radial Stator-to-Rotor forces to cause shaft wobble.
- The ThinGap design is very tolerant of mismatch in the relative axial position of the Rotor versus the Stator.
High Inertia Rotor
- Rotating both the outer and inner irons of the motor has the additional benefit of raising the inertia, especially on models where the magnets are outside the stator. The high inertia helps damp out any transients and provides smooth motion even in applications such as pumps where periodic mechanical forces are encountered.
Stator Physical Design
- The coil is not backed by iron, allowing excellent air flow over both sides of the coil.
- Airflow over the coil is excellent due to the rotation of the Rotor irons and magnets.
- ThinGap Embedded Motor Stators are far more consistent from unit-to-unit – no random effects due to the chance positioning of wires
