Forklift Drive Motor - MCC's or Motor Control Centersare an assembly of one or more sections that contain a common power bus. These have been utilized in the auto business since the 1950's, in view of the fact that they were utilized many electric motors. Now, they are utilized in various commercial and industrial applications.
In factory assembly for motor starter; motor control centers are fairly common practice. The MCC's consist of variable frequency drives, programmable controllers and metering. The MCC's are commonly used in the electrical service entrance for a building. Motor control centers frequently are used for low voltage, 3-phase alternating current motors that vary from 230 volts to 600 volts. Medium voltage motor control centers are designed for large motors that vary from 2300 volts to 15000 volts. These units make use of vacuum contractors for switching with separate compartments in order to accomplish power control and switching.
Inside factory locations and area that have dusty or corrosive processing, the MCC can be installed in climate controlled separated locations. Typically the MCC will be located on the factory floor near 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. So as to complete maintenance or testing, extremely big controllers could be bolted into place, whereas smaller controllers could be unplugged from the cabinet. Every motor controller consists of a solid state motor controller or a contractor, overload relays In order to protect the motor, fuses or circuit breakers so as to provide short-circuit protection and a disconnecting switch in order to isolate the motor circuit. Separate connectors enable 3-phase power in order to enter the controller. The motor is wired to terminals situated inside the controller. Motor control centers supply wire ways for power cables and field control.
Each and every motor controller inside a motor control center could be specified with a range of choices. These alternatives consist of: control switches, pilot lamps, separate control transformers, extra control terminal blocks, and numerous types of bi-metal and solid-state overload protection relays. They even comprise various classes of types of power fuses and circuit breakers.
Regarding the delivery of motor control centers, there are lots of options 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. On the other hand, they could be provided set for the client to connect all field wiring.
Motor control centers normally sit on the floor and must have a fire-resistance rating. Fire stops can be needed for cables which go through fire-rated floors and walls.
