What makes a motor hard to spin?

[suicideneil]

Its a commonly asked question, and the simple answer is down to the design of the motor- slotted vs slottless.

Slottless motors like feigaos and hackers are much easier to spin by hand compared to slotted stator motors like neus and medusas.

The slots on those motors foucus the magnetic field much more intensly, creating a defined notchyness as it rotates; slotless motors dont focus the magnetic field in the same way, so you dont really feel the rotor (magnets) aligning to the windings inside the motor as you spin it.

The Tekno motors are slotted stator designs, but the slots are spaced differently giving a less pronounced feeling of notchyness.
