Motor control panel design refers to a specific type of electrical control panel, generally used in commercial and industrial settings where a bank of electric motors demand a centrally located control centre. Usually referred to as a Motor Control Centre, or MCC. The MCC may be a separate or segregated area such as an air conditioned electrical room, or may well be on the factory floor, near the machinery being controlled.
The design process for an MCC system is very involved, intricate work which will need a motor control panel design company that has experience with the very specific requirements demanded by such control systems. DualTEC are one of the UK’s leading electrical engineering companies, with an in-depth knowledge of MCC design and their related industries.
MCC design considerations
As previously mentioned, motor control panel design is an involved process with a wide range of parts and specifications to be taken into consideration. These can be broken down into five main areas, the first of which we’ve already touched on – the motor control centre. This usually involves a series of enclosed panel sections, connected via a common power bus. Each individual section will contain a motor starter, breaker or fuse box and a power disconnect. More intricate systems might also include PLCs, HMIs, VFDs, indication lights and push buttons – depending on the function and intended user. The remaining five considerations tend to be:
Customer Specifications – The finished control panel as well as the design will range significantly depending on the customers requirements, the most common deciding factor being the end user. Some components, especially programmable controllers and human-machine interfaces, are only used in certain situations, the inclusion of such parts can significantly change the design and budget of the panel.
Voltage Range – The MCC has to be designed specifically for the operating voltage of the motors in operation. This can range from low voltage systems running between 200 and 600 volts, to systems with motors running in the 2300 and 15000 volt range. With such disparity in voltage range, the motors intended to be used must inform the design phase.
Usage Environment – Initially used in the car manufacturing industry, where assembly lines required multiple electric motors and thusly a central location for control. The MCC has evolved in to use for multiple commercial and industrial applications. If the usage environment is particularly dirty, the MCC may be installed in its own enclosed, clean area. But generally speaking, the control panel will be in close proximity to the motors in question.
Fire Safety – All electrical equipment – whether a motor or control panel – poses a potential fire hazard, no matter how well built. Given how MCCs are generally installed near moving machinery and directly on to the factory floor, they often need to have a fire-resistance rating as standard. During the design phase, the location of the panel within its environment should be very carefully considered, making safety a priority. Similarly, the inclusion of industry-standard components, graded to the relevant BS standards should be an absolute priority during the building phase.
Choose the right company for the job
If your company works within any form of manufacturing industry that depends on multiple motors to keep the production line running smoothly, you may well be looking for a motor control panel design company. Whether you’re a new business and need an entire MCC designing, or whether your system is out of date and in need of a redesign – DualTEC have a wealth of experience in motor control design that allows us to provide an outstanding, unbeatable service.
