Drive Motor for Forklifts - Motor Control Centers or likewise called MCC's, are an assembly of one or more enclosed sections, that have a common power bus principally consisting of motor control units. They have been utilized ever since the 1950's by the automobile business, since they used many electric motors. These days, they are used in a variety of industrial and commercial applications.
Within factory assembly for motor starter; motor control centers are rather common technique. The MCC's consist of variable frequency drives, programmable controllers and metering. The MCC's are commonly seen in the electrical service entrance for a building. Motor control centers commonly are utilized for low voltage, 3-phase alternating current motors that range from 230 volts to 600 volts. Medium voltage motor control centers are made for large motors that range from 2300 volts to 15000 volts. These units make use of vacuum contractors for switching with separate compartments to be able to accomplish 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 next to the equipment 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 can be unplugged from the cabinet to complete maintenance or testing, while extremely big controllers can be bolted in place. Each and every motor controller consists of a solid state motor controller or a contractor, overload relays so as to protect the motor, fuses or circuit breakers in order to provide short-circuit protection and a disconnecting switch in order to isolate the motor circuit. Separate connectors allow 3-phase power to enter the controller. The motor is wired to terminals positioned in the controller. Motor control centers offer wire ways for power cables and field control.
Every motor controller within a motor control center could be specified with a range of alternatives. These alternatives consist of: control switches, pilot lamps, separate control transformers, extra control terminal blocks, and various types of solid-state and bi-metal overload protection relays. They also comprise different classes of kinds of circuit breakers and power fuses.
Regarding the delivery of motor control centers, there are many choices for the consumer. These can be delivered as an engineered assembly with a programmable controller together with internal control or with interlocking wiring to a central control terminal panel board. Conversely, they can be provided ready for the client to connect all field wiring.
MCC's usually sit on floors which must have a fire-resistance rating. Fire stops may be needed for cables which go through fire-rated floors and walls.
