TF34-GE-2. Initial variant for Lockheed S-3, entered production in August 1972. TF34-GE-100. Variant for Fairchild A-10A, first flown in A-10 during May 1972. Production began in October 1974. TF34-GE-400A. Improved version of GE-2 for Lockheed S-3.
In 2014 Rotork acquired Young Tech Co. Ltd. (YTC), a Korean instrumentation manufacturer. [17] In 2014 Rotork also acquired Xylem Flow Control Limited (XFC), based in Wolverhampton, UK, a leading manufacturer of solenoid valves and instruments under the Midland-ACS, Alcon Solenoid Valves and Landon Kingsway brands for £18 million.

The original design, created by Rein Narma as he was building Les Paul's first 8-channel mixing console, was licensed by Sherman Fairchild who hired Rein Narma as the company's chief engineer. [2] The company's products also included amplifiers, preamplifiers, a control track generator to synchronize tape recorders, [3] and recording lathes. [4]
Servo motors and stepper motors are specialist types of fractional-horsepower electric motors usually intended for high-precision or robotics applications. Usually running from a DC supply, when combined with a planetary gearbox can offer accuracies less than 8 arc-minutes (2 ⁄ 15 ths of a degree, or approx. 2.3 milliradians). Due to their ...
FCM8531 - Rapid, Easy Conversion to PMSM/BLDC Motor Control (Photo: Business Wire) To help designers with these cost and software burdens, Fairchild Semiconductor (NYS: FCS) developed the FCM8531 ...
An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor that produces torque is obtained by electromagnetic induction from the magnetic field of the stator winding. [1] An induction motor therefore needs no electrical connections to the rotor.
A linear motor is an electric motor that has had its stator and rotor "unrolled", thus, instead of producing a torque , it produces a linear force along its length. However, linear motors are not necessarily straight. Characteristically, a linear motor's active section has ends, whereas more conventional motors are arranged as a continuous loop.
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 ...
