MOTOR CONTROL CIRCUIT DIAGRAM SYMBOLS

Electronic Circuit Symbols - Components and Schematic Diagram Symbols
Electronic Component: Circuit Symbol: Description: Resistor: Resistor Circuit Symbol: A resistor is used to restrict the amount of current flow through a device. Abbreviated as ‘R’. Rheostat: Rheostat Circuit Symbol: A rheostat is used to control the current flow with two contacts. Applicable in controlling lamp brightness, capacitor charge rate, etc.
AC Motor Control Circuits Worksheet - AC Electric Circuits
Notes: This circuit is known as a latching circuit, because it “latches” in the “on” state after a momentary action. The contact in parallel with the “Run” switch is often referred to as a seal-in contact, because it “seals” the momentary condition of the Run switch closure after that switch is de-actuated. The follow-up question of how we may make the motor stop running is a

Speed Control of DC Motor - Voltage, Rheostatic & Flux Control
Speed Control of DC Series Motor. Speed control of DC series motor is done by the armature control and field control methods. Armature Resistance control method for DC series motor. In this method, a variable resistor or rheostat connected in series with armature resistor. The circuit diagram of this method is as shown in the below figure.
Smps Circuit Diagram Power Supply
May 02, 2016Circuit Diagram Of Smps Power Supply DC-DC. The output of the smps is regulated by means of PWM (Pulse-Width-Modulation). As given in the circuit above, the switch can be driven by the PWM-oscillator, such that the power delivered to the step-down transformer is controlled indirectly, & hence, the output is controlled by the pulse-width-modulation, as this
MOTOR CIRCUITS AND CONTROL – Applied Industrial Electricity
A contactor is a large relay, usually used to switch current to an electric motor or another high-power load.; Large electric motors can be protected from overcurrent damage through the use of overload heaters and overload contacts the series-connected heaters get too hot from excessive current, the normally-closed overload contact will open, de-energizing the contactor [PDF]
