A Japanese police car with a PATLITE AWS light bar NEXCO East Japan patrol car with amber and red light bar. Red is the most used color on Japanese emergency vehicles. Japanese police use light bars mounted on a raised (mechanical) platform to make them more visible over congested streets. Rotating lights are most commonly used.
The shaded-pole motor is the original type of AC single-phase motor, dating back to at least as early as 1890. [ 1] A shaded-pole motor is a motor, in which the auxiliary winding is composed of a copper ring or bar surrounding a portion of each pole to produce a weakly rotating magnetic field. [ 2] When single phase AC supply is applied to the ...
A squirrel-cage rotor is the rotating part of the common squirrel-cage induction motor. It consists of a cylinder of steel laminations, with aluminum or copper conductors embedded in its surface. In operation, the non-rotating stator winding is connected to an alternating current power source; the alternating current in the stator produces a ...
A series of devices connected in a daisy chain layout. In electrical and electronic engineering, a daisy chain is a wiring scheme in which multiple devices are wired together in sequence or in a ring, [ 1] similar to a garland of daisy flowers. Daisy chains may be used for power, analog signals, digital data, or a combination thereof.
The induction motor stator's magnetic field is therefore changing or rotating relative to the rotor. This induces an opposing current in the rotor, in effect the motor's secondary winding. [28] The rotating magnetic flux induces currents in the rotor windings, [29] in a manner similar to currents induced in a transformer's secondary winding(s).
Rotary encoder. A Gray code absolute rotary encoder with 13 tracks. At the top, the housing, interrupter disk, and light source can be seen; at the bottom the sensing element and support components. A rotary encoder, also called a shaft encoder, is an electro-mechanical device that converts the angular position or motion of a shaft or axle to ...
Trailer connectors between the trailer and passenger car, light truck or heavy trucks with 12V systems. In Europe, both 7-pin (ISO 1724) and 13-pin (ISO 11446) are common. The 13-pin version being phased in is newer, provides more services than the 7-pin, a more positive locking and also better protection against moisture and contamination.
A Halbach array ( German: [ˈhalbax]) is a special arrangement of permanent magnets that augments the magnetic field on one side of the array while cancelling the field to near zero on the other side. [1] [2] This is achieved by having a spatially rotating pattern of magnetisation. The rotating pattern of permanent magnets (on the front face ...
