Forklift Drive Motor - MCC's or also known as Motor Control Centersare an assembly of one section or more that include a common power bus. These have been used in the vehicle industry ever since the 1950's, because they were utilized lots of electric motors. Nowadays, they are utilized in a variety of industrial and commercial applications.
Inside factory assembly for motor starter; motor control centers are somewhat common method. The MCC's comprise variable frequency drives, programmable controllers and metering. The MCC's are normally found in the electrical service entrance for a building. Motor control centers frequently are used for low voltage, 3-phase alternating current motors which vary from 230 volts to 600 volts. Medium voltage motor control centers are intended for big motors that vary from 2300 volts to 15000 volts. These units make use of vacuum contractors for switching with separate compartments so as to achieve power switching and control.
Inside factory area and locations that 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 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. In order to complete maintenance or testing, extremely big controllers could be bolted into place, while smaller controllers may be unplugged from the cabinet. Every motor controller consists of a contractor or a solid state motor controller, overload relays to protect the motor, fuses or circuit breakers to supply short-circuit protection and a disconnecting switch to be able to isolate the motor circuit. Separate connectors allow 3-phase power so as to enter the controller. The motor is wired to terminals positioned inside the controller. Motor control centers supply wire ways for field control and power cables.
Each and every motor controller within a motor control center can be specified with a range of alternatives. These options consist of: extra control terminal blocks, control switches, pilot lamps, separate control transformers, as well as numerous kinds of solid-state and bi-metal overload protection relays. They even comprise different classes of kinds of power fuses and circuit breakers.
Concerning the delivery of motor control centers, there are many 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 provided prepared for the customer to connect all field wiring.
MCC's generally sit on floors which must have a fire-resistance rating. Fire stops may be required for cables that go through fire-rated walls and floors.
