Forklift Drive Motor - MCC's or likewise known as Motor Control Centersare an assembly of one section or more which have a common power bus. These have been used in the vehicle business ever since the 1950's, since they were utilized lots of electric motors. Nowadays, they are used in a variety of industrial and commercial applications.
Motor control centers are a modern method in factory assembly for some motor starters. This particular machinery could include variable frequency drives, programmable controllers and metering. The MCC's are normally seen in the electrical service entrance for a building. Motor control centers frequently are utilized for low voltage, 3-phase alternating current motors that vary from 230 volts to 600 volts. Medium voltage motor control centers are made for big motors that range from 2300V to 15000 V. These units utilize vacuum contractors for switching with separate compartments so as to attain power switching and control.
Within factory area and locations which have corrosive or dusty processing, the MCC could be installed in climate controlled separated locations. Normally the MCC will be positioned on the factory floor adjacent to the machinery 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 may be unplugged from the cabinet to complete maintenance or testing, whereas really big controllers could be bolted in place. Each motor controller consists of a solid state motor controller or a contractor, overload relays to be able to protect the motor, circuit breaker or fuses 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 within the controller. Motor control centers provide wire ways for field control and power cables.
Each and every motor controller in a motor control center could be specified with different choices. These options comprise: separate control transformers, extra control terminal blocks, control switches, pilot lamps, as well as many kinds of bi-metal and solid-state overload protection relays. They even have different classes of types of power fuses and circuit breakers.
There are various alternatives 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 along with internal control. Conversely, they can be supplied prepared for the customer to connect all field wiring.
Motor control centers normally sit on the floor and should have a fire-resistance rating. Fire stops can be necessary for cables which go through fire-rated walls and floors.
