The stationary (stator) windings of an outrunner motor are excited by conventional DC brushless motor controllers. A direct current (switched on and off at high frequency for voltage modulation) is typically passed through three or more non-adjacent windings together, and the group so energized is alternated electronically based upon rotor position feedback.
The motor from a 3.5 in floppy disk drive. The coils, arranged radially, are made from copper wire coated with blue insulation. The rotor (upper right) has been removed and turned upside-down. The gray ring inside its cup is a permanent magnet. This particular motor is an outrunner, with the stator inside the rotor. DC brushless ducted fan. The ...
A brushless, geared inrunner motor in a quadcopter. The term inrunner refers to an electric motor where the rotor (runner) is inside the stator. The term is in particular used for brushless motors to differentiate them from outrunners that have their rotor outside the stator. The vast majority of electric motors are inrunners.

The motor size constant and motor velocity constant (, alternatively called the back EMF constant) are values used to describe characteristics of electrical motors. Motor constant [ edit ]
Consumer stocks 2025: Watch out for discount retailers and fast casual chains, tariffs remain a wild card
They rotate the wheel either through an axial, inrunner, or outrunner rotor design, with either brushed or brushless commutator design. [18] Honda FCX Concept 2005 in-wheel motor with high-voltage wires in orange. Running high voltage outside the chassis can be avoided by using near-wheel motors, which have similar advantages to in-wheel motors.

Visually it is nearly identical to the 14B-T but can be distinguished by having no external piston-cooling oil nozzles as found on the 3Bii, 14B and 14B-T versions of the engine block. Both '3B' and '14B' castings are machined off the engine block replaced by a simple '15B' stamp, and a separate '15' casting behind the diesel injection pump.
