  2. Variable force solenoid - Wikipedia

    en.wikipedia.org/wiki/Variable_force_solenoid

    A variable force solenoid (VFS) is an electro-hydraulic device that controls pressure proportionally or inversely proportionally to a signal (voltage or current) obtained from the on-board controller of a powertrain. A low flow VFS is used as a signal level devices for transmission line pressure control or application of clutches.

  3. Transmission solenoid - Wikipedia

    en.wikipedia.org/wiki/Transmission_solenoid

    A transmission solenoid or cylinoid is an electro-hydraulic valve that controls fluid flow into and throughout an automatic transmission. Solenoids can be normally open or normally closed. They operate via a voltage or current supplied by the transmission computer or controller.

  4. Solenoid (engineering) - Wikipedia

    en.wikipedia.org/wiki/Solenoid_(engineering)

    The solenoid can be useful for positioning, stopping mid-stroke, or for low velocity actuation; especially in a closed loop control system. A uni-directional solenoid would actuate against an opposing force or a dual solenoid system would be self cycling. The proportional concept is more fully described in SAE publication 860759 (1986).

  5. Solenoid - Wikipedia

    en.wikipedia.org/wiki/Solenoid

    This equation is valid for a solenoid in free space, which means the permeability of the magnetic path is the same as permeability of free space, μ 0. If the solenoid is immersed in a material with relative permeability μ r, then the field is increased by that amount: =.

  6. Solenoid valve - Wikipedia

    en.wikipedia.org/wiki/Solenoid_valve

    A small solenoid can generate a limited force. An approximate relationship between the required solenoid force F s, the fluid pressure P, and the orifice area A for a direct acting solenoid valve is: [3] = = where d is the orifice diameter. A typical solenoid force might be 15 N (3.4 lb f).

  7. Vector control (motor) - Wikipedia

    en.wikipedia.org/wiki/Vector_control_(motor)

    In vector control, an AC induction or synchronous motor is controlled under all operating conditions like a separately excited DC motor. [21] That is, the AC motor behaves like a DC motor in which the field flux linkage and armature flux linkage created by the respective field and armature (or torque component) currents are orthogonally aligned such that, when torque is controlled, the field ...

    en.wikipedia.org/wiki/GM_6L_transmission

    The 6L 50 (and similar 6L 45) is a 6-speed longitudinally-mounted automatic transmission produced by General Motors.It is very similar in design to the larger GM 6L 80 and 6L 90, and is produced at GM Powertrain plants in Toledo, Ohio; Silao, Guanajuato, Mexico; and by the independent Punch Powerglide company in Strasbourg, France.
