Drive Motor for Forklifts - MCC's or otherwise known as Motor Control Centersare an assembly of one or more sections that contain a common power bus. These have been used in the automobile industry ever since the 1950's, as they were made use of lots of electric motors. Now, they are used in a variety of commercial and industrial applications.
Motor control centers are a modern method in factory assembly for several motor starters. This machinery can comprise variable frequency drives, programmable controllers and metering. The MCC's are usually used in the electrical service entrance for a building. Motor control centers often are used for low voltage, 3-phase alternating current motors that vary from 230 V to 600V. Medium voltage motor control centers are made for big motors which range from 2300V to 15000 V. These units use vacuum contractors for switching with separate compartments to be able to attain power switching and control.
In areas where extremely corrosive or dusty methods are occurring, the motor control center may be established in a separate air-conditioned room. Usually the MCC will be situated on the factory floor next 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 testing or maintenance, really large controllers could be bolted into place, whereas smaller controllers could be unplugged from the cabinet. Each motor controller has a contractor or a solid state motor controller, overload relays In order to protect the motor, circuit breaker or fuses to provide short-circuit protection and a disconnecting switch so as to isolate the motor circuit. Separate connectors enable 3-phase power so as to enter the controller. The motor is wired to terminals positioned in the controller. Motor control centers provide wire ways for field control and power cables.
Each motor controller in a motor control center could be specified with different alternatives. These alternatives include: separate control transformers, extra control terminal blocks, control switches, pilot lamps, as well as numerous kinds of solid-state and bi-metal overload protection relays. They likewise comprise various classes of types of circuit breakers and power fuses.
There are a lot of choices 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 supplied prepared for the client to connect all field wiring.
MCC's usually sit on floors which are required to have a fire-resistance rating. Fire stops can be required for cables which penetrate fire-rated walls and floors.
