Are larger motor wheels faster or smaller ones?

[StAaron]

Larger wheels provide higher speed. Here is relevant information about motors: 1. Working principle: The direction of conductor force is determined by the left-hand rule. This pair of electromagnetic forces forms a torque acting on the armature, known as electromagnetic torque in rotating motors. The torque direction is counterclockwise, attempting to rotate the armature counterclockwise. If this electromagnetic torque can overcome the resistance torque on the armature (such as friction-induced resistance torque and load torque), the armature can rotate counterclockwise. 2. DC motor: The excitation method of DC motors refers to how the excitation winding is powered to generate excitation magnetomotive force and establish the main magnetic field.
