Drive Motor for Forklifts - MCC's or also known as Motor Control Centersare an assembly of one or more sections which include a common power bus. These have been utilized in the automobile industry ever since the 1950's, since they were used many electric motors. These days, they are utilized in other industrial and commercial applications.
Motor control centers are a modern method in factory assembly for some motor starters. This machine could consist of programmable controllers, metering and variable frequency drives. The MCC's are commonly found in the electrical service entrance for a building. Motor control centers frequently are used for low voltage, 3-phase alternating current motors which vary from 230 volts to 600 volts. Medium voltage motor control centers are made for big motors which range from 2300V to 15000 V. These units utilize vacuum contractors for switching with separate compartments to be able to attain power control and switching.
In areas where extremely dusty or corrosive methods are taking place, the motor control center can be installed in a separate air-conditioned room. Usually the MCC would be situated on the factory floor adjacent to the machines it is controlling.
A MCC has one or more vertical metallic cabinet sections with power bus and provisions for plug-in mounting of individual motor controllers. Smaller controllers could be unplugged from the cabinet in order to complete testing or maintenance, whereas very big controllers could be bolted in place. Each and every motor controller has a solid state motor controller or a contractor, overload relays to protect the motor, circuit breaker or fuses in order to provide short-circuit protection as well as a disconnecting switch to be able to isolate the motor circuit. Separate connectors allow 3-phase power to enter the controller. The motor is wired to terminals situated inside the controller. Motor control centers offer wire ways for field control and power cables.
Inside a motor control center, each and every motor controller could be specified with a lot of various choices. Some of the choices include: pilot lamps, separate control transformers, extra control terminal blocks, control switches, and numerous kinds of bi-metal and solid-state overload protection relays. They likewise have various classes of types of power fuses and circuit breakers.
There are a lot of choices concerning delivery of MCC's to the customer. They could be delivered as an engineered assembly with interlocking wiring to a central control terminal panel board or programmable controller together with internal control. On the other hand, they could be provided ready for the client to connect all field wiring.
MCC's generally sit on floors that are required to have a fire-resistance rating. Fire stops could be required for cables that penetrate fire-rated floors and walls.
