There are several factors that affect the life and cost of operation of a motor. When motors are started there is mechanical stress imposed on the motor. The starting current peaks and maximum power is needed from the supply system to operate the motor. Your electric bill is affected by this demand that is put on your electrical system as the motor is started. The larger the motor the larger the demand put on the system. Operating costs and motor stress can be lowered by reducing the starting current of the motor. Older motors and starters are being replaced with variable frequency drives and soft starters to reduce starting current spikes and mechanical stress on the motor. Newer motors are built to operate efficiently with electronic starters. It is important to know all the elements of the control system that are affected by the motor operation when replacing the motor controls. Monitoring systems can be installed to ensure the motor is running properly and signal when maintenance is needed. When motor operation is critical to a process it is important that it is well maintained and working efficiently. Many control systems have communications systems integrated within the operation to signal maintenance people that there is a failure. It is important that your electrical contractor understand how these systems function and how to install them correctly.
