Drive Motor for Forklifts - MCC's or also known as Motor Control Centersare an assembly of one section or more that contain a common power bus. These have been used in the automobile trade since the 1950's, for the reason that they were utilized a large number of electric motors. Today, they are used in various industrial and commercial applications.
Motor control centers are a modern technique in factory assembly for several motor starters. This machine could comprise metering, variable frequency drives and programmable controllers. The MCC's are commonly seen in the electrical service entrance for a building. Motor control centers often are used for low voltage, 3-phase alternating current motors that range from 230 volts to 600 volts. Medium voltage motor control centers are designed for big motors which range from 2300V to 15000 V. These units utilize vacuum contractors for switching with separate compartments so as to attain power control and switching.
Inside factory locations and area which have dusty or corrosive processing, the MCC can be installed in climate controlled separated locations. Normally the MCC will be positioned on the factory floor next 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, very large controllers can be bolted into place, whereas smaller controllers can be unplugged from the cabinet. Each motor controller has a solid state motor controller or a contractor, overload relays so as to protect the motor, circuit breaker or fuses to supply short-circuit protection and a disconnecting switch so as to isolate the motor circuit. Separate connectors allow 3-phase power so as to enter the controller. The motor is wired to terminals located inside the controller. Motor control centers offer wire ways for field control and power cables.
Inside a motor control center, each motor controller can be specified with many different choices. Some of the choices consist of: pilot lamps, separate control transformers, extra control terminal blocks, control switches, and numerous kinds of bi-metal and solid-state overload protection relays. They likewise have different classes of kinds of circuit breakers and power fuses.
Regarding the delivery of motor control centers, there are various options for the customer. 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. On the other hand, they could be supplied ready for the client to connect all field wiring.
Motor control centers usually sit on the floor and must have a fire-resistance rating. Fire stops may be required for cables that go through fire-rated floors and walls.
