Understanding motor control circuits

This unit discusses the basic concepts of motor control , including “ motor control language” and the types of wiring diagrams used. Motor control circuits are an effective way to reduce cost by using smaller wire and reduced-amperage devices . How, exactly, do overload heaters protect an electric motor against “burnout” from . This video is an introduction to how 3-phase motors are typically controlled in commercial and industrial applications. In addition to motor control , this vi.

In this section we will study the electrical (but not electronic) control of 3-phase alternating current motors.

Our study is limited to elementary circuits because industrial circuits are usually too intricate to explain briefly.

However, the basic principles covered here apply to any system of control , no matter how complex it may . Wiring diagrams show the connections to the controller , while line diagrams show circuits of the operation of the controller. The difference between AC and DC power. All explanation of single and three phase power.

The function of common electrical components found in small water systems. Common pump electrical control components. When power is restore the Start button must be operated again before the motor will restart.

Basic Electricity and Motor Controls. The term “3-wire” control is derived from the fact that in the basic circuit , at least three wires are required to connect the pilot devices to the starter. Wire Control : Maintained Contact Hand-OFF-Auto Selector Switch. The full Motor Controls Training Software - The MCTrainer (hours) contains sections on.

Please visit MikeHoltNEC channel to view additional video material. This is frequently the case with farm machinery. Circuit breakers are subject to failure after repeated on and off cycling and. Understanding the operation and components of a. Learning 1- Basics of Motors and Motor Controls. There are two basic types of control circuits : three-wire and two-wire.

These designations stem from the fact that for three-wire circuit control , only three wires are required from the ordinary across the line motor starter to the control components. In two-wire control , only two wires are required.
