Forklift Drive Motor - MCC's or otherwise known as Motor Control Centersare an assembly of one or more sections that have a common power bus. These have been utilized in the auto business ever since the 1950's, in view of the fact that they were used a large number of electric motors. Nowadays, they are utilized in various commercial and industrial applications.
Motor control centers are a modern practice in factory assembly for several motor starters. This equipment could comprise variable frequency drives, programmable controllers and metering. The MCC's are commonly seen in the electrical service entrance for a building. Motor control centers often are utilized for low voltage, 3-phase alternating current motors which range from 230 V to 600V. Medium voltage motor control centers are made for large motors which vary from 2300V to 15000 V. These units make use of vacuum contractors for switching with separate compartments so as to achieve power switching and control.
Inside factory locations and area that have dusty or corrosive processing, the MCC can be installed in climate controlled separated locations. Usually the MCC would be located 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 complete testing or maintenance, extremely big controllers can be bolted into place, whereas smaller controllers can be unplugged from the cabinet. Each motor controller consists of a contractor or a solid state motor controller, overload relays so as to protect the motor, circuit breaker or fuses to supply short-circuit protection as well as a disconnecting switch so as to isolate the motor circuit. Separate connectors allow 3-phase power to enter the controller. The motor is wired to terminals positioned inside the controller. Motor control centers provide wire ways for power cables and field control.
Within a motor control center, each and every motor controller can be specified with many various alternatives. Some of the alternatives consist of: pilot lamps, separate control transformers, extra control terminal blocks, control switches, and many types of bi-metal and solid-state overload protection relays. They likewise comprise various classes of kinds of circuit breakers and power fuses.
Regarding the delivery of motor control centers, there are various choices for the consumer. 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 can be supplied set for the customer to connect all field wiring.
Motor control centers typically sit on the floor and should have a fire-resistance rating. Fire stops can be required for cables which go through fire-rated floors and walls.
