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.
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 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 ...

Offered in the unusual capacity of 1.7 L as well as 2.0 L, it proved to be reliable and was widely used in BL vehicles. These included the rear wheel drive Morris Ital of 1980 (1.7 L or 2.0 L with an automatic gear box), the rear wheel drive Rover SD1 of 1982 (2.0 L only), and 1.7 L and 2.0 L in the front wheel drive Austin Ambassador – in fact the only engine offered in this model.
The 4HF1-CNG is a CNG engine of 4.334 L capacity (as based on direct injection diesel engine) with non-contact ignition system. Peak torque is 323 Nm, peak power is 120 PS (88 kW) at 1,500 rpm. Bore is 115 mm, stroke is 108 mm. The 4HV1 is a CNG engine of 4.570 L capacity with non-contact ignition system. Peak torque is 353 Nm, peak power is ...
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.
