  2. Servomechanism - Wikipedia

    en.wikipedia.org/wiki/Servomechanism

    1. electric motor. 2. position feedback potentiometer. 3. reduction gear. 4. actuator arm. A servomotor is a specific type of motor that is combined with a rotary encoder or a potentiometer to form a servomechanism. This assembly may in turn form part of another servomechanism.

  3. Electronic speed control - Wikipedia

    en.wikipedia.org/wiki/Electronic_speed_control

    An electronic speed control follows a speed reference signal (derived from a throttle lever, joystick, or other manual input) and varies the switching rate of a network of field effect transistors (FETs). [1] By adjusting the duty cycle or switching frequency of the transistors, the speed of the motor is changed. The rapid switching of the ...

  4. Dahlander pole changing motor - Wikipedia

    en.wikipedia.org/wiki/Dahlander_pole_changing_motor

    A Dahlander motor (also known as a pole changing motor, dual- or two speed-motor) is a type of multispeed three-phase induction motor, in which the speed of the motor is varied by altering the number of poles; this is achieved by altering the wiring connections inside the motor. The motor may have fixed or variable torque depending on the ...

  5. Instruction pipelining - Wikipedia

    en.wikipedia.org/wiki/Instruction_pipelining

    Instruction 2 would be fetched at t 2 and would be complete at t 6. The first instruction might deposit the incremented number into R5 as its fifth step (register write back) at t 5. But the second instruction might get the number from R5 (to copy to R6) in its second step (instruction decode and register fetch) at time t 3. It seems that the ...

  6. Pentium II - Wikipedia

    en.wikipedia.org/wiki/Pentium_II

    The Pentium II[ 2] brand refers to Intel 's sixth-generation microarchitecture ("P6") and x86 -compatible microprocessors introduced on May 7, 1997. Containing 7.5 million transistors (27.4 million in the case of the mobile Dixon with 256 KB on-die L2 cache ), the Pentium II featured an improved version of the first P6 -generation core of the ...

  7. Complex instruction set computer - Wikipedia

    en.wikipedia.org/wiki/Complex_instruction_set...

    Complex instruction set computer. A complex instruction set computer ( CISC / ˈsɪsk /) is a computer architecture in which single instructions can execute several low-level operations (such as a load from memory, an arithmetic operation, and a memory store) or are capable of multi-step operations or addressing modes within single instructions ...

  8. Control system - Wikipedia

    en.wikipedia.org/wiki/Control_system

    Its name comes from the information path in the system: process inputs (e.g., voltage applied to an electric motor) have an effect on the process outputs (e.g., speed or torque of the motor), which is measured with sensors and processed by the controller; the result (the control signal) is "fed back" as input to the process, closing the loop.

  9. Setpoint (control system) - Wikipedia

    en.wikipedia.org/wiki/Setpoint_(control_system)

    In cybernetics and control theory, a setpoint ( SP; [ 1] also set point) is the desired or target value for an essential variable, or process value (PV) of a control system, [ 2] which may differ from the actual measured value of the variable. Departure of such a variable from its setpoint is one basis for error-controlled regulation using ...
