[3] [5] [6] Another common circle diagram form is as described in the two constant air-gap induction motor images shown here, [7] [8] where, R s, X s: Stator resistance and leakage reactance; R r ', X r ', s: Rotor resistance and leakage reactance referred to the stator and rotor slip; R c, X m, : Core and mechanical losses, magnetization reactance
A diagram which shows the interconnection of process equipment and the instrumentation used to control the process. In the process industry, a standard set of symbols is used to prepare drawings of processes. The instrument symbols used in these drawings are generally based on International Society of Automation (ISA) Standard S5.1
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 ...
ISO 14617 Graphical symbols for diagrams is a library of graphical symbols for diagrams used in technical applications. [1] ISO 14617 consists of the following parts: Part 1: General information and indexes; Part 2: Symbols having general application; Part 3: Connections and related devices; Part 4: Actuators and related devices
88 - Auxiliary Motor or Motor Generator; 89 - Line Switch; 90 - Regulating Device; 91 - Voltage Directional Relay; 92 - Voltage And Power Directional Relay; 93 - Field-Changing Contactor; 94 - Tripping or Trip-Free Relay; 95 – Trip Circuit Healthy; 96 – Transmitter; 97 – For specific applications where other numbers are not suitable
Wire crossover symbols for circuit diagrams. The CAD symbol for insulated crossing wires is the same as the older, non-CAD symbol for non-insulated crossing wires. To avoid confusion, the wire "jump" (semi-circle) symbol for insulated wires in non-CAD schematics is recommended (as opposed to using the CAD-style symbol for no connection), so as to avoid confusion with the original, older style ...

A motor controller is a device or group of devices that can coordinate in a predetermined manner the performance of an electric motor. [1] A motor controller might include a manual or automatic means for starting and stopping the motor, selecting forward or reverse rotation, selecting and regulating the speed, regulating or limiting the torque, and protecting against overloads and electrical ...
