Drive Motor for Forklifts - Motor Control Centers or otherwise called MCC's, are an assembly of one or more enclosed sections, which have a common power bus mainly containing motor control units. They have been utilized ever since the 1950's by the auto trade, since they used a lot of electric motors. These days, they are used in a variety of commercial and industrial applications.
Inside factory assembly for motor starter; motor control centers are quite common practice. The MCC's include variable frequency drives, programmable controllers and metering. The MCC's are commonly seen in the electrical service entrance for a building. Motor control centers frequently are used for low voltage, 3-phase alternating current motors that range from 230 V to 600V. Medium voltage motor control centers are made for big motors which range from 2300 volts to 15000 volts. These units use vacuum contractors for switching with separate compartments in order to achieve power switching and control.
Within factory area and locations which have corrosive or dusty processing, the MCC could be installed in climate controlled separated locations. Usually the MCC would be positioned on the factory floor near the machines it is controlling.
For plug-in mounting of individual motor controls, A motor control center has one or more vertical metal cabinet sections with power bus. So as to complete maintenance or testing, very large controllers could be bolted into place, whereas smaller controllers could be unplugged from the cabinet. Every motor controller consists of a contractor or a solid state motor controller, overload relays to protect the motor, circuit breaker or fuses to provide short-circuit protection as well as a disconnecting switch to be able to isolate the motor circuit. Separate connectors enable 3-phase power so as to enter the controller. The motor is wired to terminals positioned inside the controller. Motor control centers provide wire ways for field control and power cables.
Within a motor control center, each and every motor controller can be specified with several different options. Some of the choices consist of: extra control terminal blocks, control switches, pilot lamps, separate control transformers, and numerous types of solid-state and bi-metal overload protection relays. They likewise comprise different classes of kinds of circuit breakers and power fuses.
Regarding the delivery of motor control centers, there are many alternatives for the customer. These could be delivered as an engineered assembly with a programmable controller along with internal control or with interlocking wiring to a central control terminal panel board. Conversely, they can be provided set for the customer to connect all field wiring.
MCC's generally sit on floors that must have a fire-resistance rating. Fire stops may be necessary for cables that go through fire-rated walls and floors.
