Magnetic Pole Pairs: Too Many Is Wasteful, Too Few Is Insufficient—Where Are The Selection Limits of Injection-Molded Ferrite Disks?

When selecting magnetic encoder disks, a common intuition is: the higher the number of pole pairs, the higher the resolution and the better the performance. At the sensor level, this judgment is broadly valid. But once the magnet material is fixed as injection-molded ferrite, the situation becomes m

Axial-Flux Rotor Magnet Demagnetization Temperature Selection: Temperature Is The First Subject of Selection

The most common mistake in magnet selection for axial-flux motors is to start from the grade table: first look at remanence, then at the maximum operating temperature, and pick a grade that is “good enough” to put into the BOM. But in an axial-flux structure, this order is exactly reversed. The roto

The “Size Triangle” of High-Speed Rotors: Outer Diameter, Stack Length, And Shaft Diameter—Why You Can’t Max Out All Three at Once

A high-speed motor or flywheel rotor sits in front of you. Outer diameter, stack length, shaft diameter—three numbers that seem like nothing more than annotations on a drawing. But in the world of high-speed rotation, these three dimensions constrain one another and form a triangle that can almost n

Selsyn Mechanical Interface Selection: Shaft Diameter, Flange And Mounting Dimensions—Precision Can Collapse with The Smallest Deviation

When the electrical parameters of a resolver are selected correctly, the system may still exhibit angle fluctuation and zero-position drift. The problem is often not in the decoding circuit but in a more hidden place: the mechanical interface. A resolver essentially measures angle through electromag
