Forklift Drive Motor - MCC's or also known as Motor Control Centersare an assembly of one section or more which have a common power bus. These have been used in the auto industry since the 1950's, in view of the fact that they were used a lot of electric motors. Nowadays, they are used in various commercial and industrial applications.
Motor control centers are a modern practice in factory assembly for several motor starters. This particular machine could include metering, variable frequency drives and programmable controllers. The MCC's are normally found in the electrical service entrance for a building. Motor control centers commonly are utilized for low voltage, 3-phase alternating current motors which range from 230 volts to 600 volts. Medium voltage motor control centers are made for large motors which vary from 2300 volts to 15000 volts. These units use vacuum contractors for switching with separate compartments to be able to achieve power switching and control.
In factory locations and area which have dusty or corrosive processing, the MCC can be installed in climate controlled separated locations. Typically the MCC will be located on the factory floor close to the equipment 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. In order to complete maintenance or testing, extremely big controllers could be bolted into place, whereas smaller controllers may be unplugged from the cabinet. Each motor controller has a contractor or a solid state motor controller, overload relays to protect the motor, circuit breaker or fuses to supply short-circuit protection as well as a disconnecting switch to be able to isolate the motor circuit. Separate connectors enable 3-phase power to enter the controller. The motor is wired to terminals located in the controller. Motor control centers provide wire ways for power cables and field control.
Inside a motor control center, each and every motor controller can be specified with lots of different options. Some of the options comprise: pilot lamps, separate control transformers, extra control terminal blocks, control switches, and numerous types of bi-metal and solid-state overload protection relays. They also have various classes of kinds of power fuses and circuit breakers.
Concerning the delivery of motor control centers, there are numerous choices for the customer. 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 could be supplied prepared for the client to connect all field wiring.
MCC's usually sit on floors which must have a fire-resistance rating. Fire stops can be necessary for cables that penetrate fire-rated floors and walls.
