Forklift Drive Motor - Motor Control Centers or otherwise called MCC's, are an assembly of one enclosed section or more, which have a common power bus mostly consisting of motor control units. They have been utilized since the 1950's by the vehicle business, as they used lots of electric motors. Nowadays, they are utilized in other industrial and commercial applications.
Within factory assembly for motor starter; motor control centers are somewhat common practice. The MCC's consist of variable frequency drives, programmable controllers and metering. The MCC's are commonly found in the electrical service entrance for a building. Motor control centers frequently are utilized for low voltage, 3-phase alternating current motors which range from 230 V to 600V. Medium voltage motor control centers are intended for large motors which vary from 2300V to 15000 V. These units utilize vacuum contractors for switching with separate compartments in order to achieve power control and switching.
Inside factory locations and area which have dusty or corrosive processing, the MCC could be installed in climate controlled separated locations. Normally the MCC will be positioned on the factory floor next to 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. To complete testing or maintenance, extremely large controllers can be bolted into place, whereas smaller controllers can be unplugged from the cabinet. Each and every motor controller consists of a solid state motor controller or a contractor, overload relays to protect the motor, fuses or circuit breakers so as to supply short-circuit protection and 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 located within the controller. Motor control centers provide wire ways for power cables and field control.
Within a motor control center, each and every motor controller could be specified with a lot of various alternatives. Some of the options comprise: pilot lamps, separate control transformers, extra control terminal blocks, control switches, and various types of solid-state and bi-metal overload protection relays. They also have different classes of kinds of power fuses and circuit breakers.
Regarding the delivery of motor control centers, there are a lot of options for the client. 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 could be supplied set for the client to connect all field wiring.
Motor control centers normally sit on the floor and must have a fire-resistance rating. Fire stops can be required for cables that penetrate fire-rated walls and floors.
