Forklift Drive Motor - MCC's or otherwise known as Motor Control Centersare an assembly of one section or more that include a common power bus. These have been utilized in the automobile industry ever since the 1950's, because they were used a lot of electric motors. Now, they are utilized in different commercial and industrial applications.
In factory assembly for motor starter; motor control centers are rather common technique. The MCC's include programmable controllers, metering and variable frequency drives. The MCC's are normally found in the electrical service entrance for a building. Motor control centers frequently are utilized for low voltage, 3-phase alternating current motors that vary from 230 volts to 600 volts. Medium voltage motor control centers are intended for big motors which range from 2300V to 15000 V. These units make use of vacuum contractors for switching with separate compartments to be able to achieve power switching and control.
Inside factory locations and area that have dusty or corrosive processing, the MCC can be installed in climate controlled separated locations. Usually the MCC would be located on the factory floor close to the machinery 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. To be able to complete maintenance or testing, very large controllers can be bolted into place, while smaller controllers can be unplugged from the cabinet. Each and every motor controller consists of a contractor or a solid state motor controller, overload relays to protect the motor, circuit breaker or fuses to supply short-circuit protection and a disconnecting switch in order to isolate the motor circuit. Separate connectors enable 3-phase power to enter the controller. The motor is wired to terminals situated within the controller. Motor control centers offer wire ways for field control and power cables.
Each and every motor controller inside a motor control center can be specified with a range of choices. These alternatives consist of: separate control transformers, extra control terminal blocks, control switches, pilot lamps, and many types of solid-state and bi-metal overload protection relays. They also have various classes of kinds of power fuses and circuit breakers.
There are a lot of options regarding delivery of MCC's to the customer. They can be delivered as an engineered assembly with interlocking wiring to a central control terminal panel board or programmable controller along with internal control. On the other hand, they could be provided prepared for the customer to connect all field wiring.
MCC's usually sit on floors which should have a fire-resistance rating. Fire stops can be required for cables that go through fire-rated floors and walls.
