Control/Drive-VFD Repair

AC Controls

Variable Frequency Drives

EMX works with customers throughout the region to identify the best possible motor drives and controls solution that will maximize the efficiency of a customer’s application. An electric motor that is matched with a properly designed motor control or drive will experience a longer motor life, less downtime and improved energy and cost savings. These results are why our technicians work with you to find the right Soft Start or VFD for your electric motor setup. The complexity and variety of VFDs means it’s critical to pair the right VFD with the right electric motor application. Our analysis includes ensuring your motor is rated for VFD use; determining cable length; filter requirements, open or closed loop, inputs and outputs.

Using a soft starter or variable frequency drive temporarily reduces the load and torque as well as the inrush current of the motor during start up. This reduces the mechanical stress on the motor and shaft, and reduces the electrodynamic forces on the attached power cables and electrical distribution network, extending the lifespan of the system.

Machine drives, primarily consisting of electric motors, pumps, and fans, account for about 50% of the manufacturing sector’s electric power consumption. The right drive system can reduce usage and energy savings quickly translate to dollars. EMX works step-by-step to provide you with the best variable frequency drive for your electric motor needs. We can even check for stray currents after installation to ensure that the motor is properly protected and does not suffer premature bearing failure.

Soft Start Controls

Electric motors incur a tremendous amount of stress during start-up process. Soft start devices, as the name indicates, help ease this stress, thereby reducing the wear and tear. While soft starters may not be as common as VFDs, there are many instances when a soft starter may be the right choice for your motor. Applications with pumps, conveyors and fans are prime candidates for soft start devices because of their characteristic stop-start nature. Soft starters minimize the start-up stress by slowly ramping up the voltage instead of blasting a static motor with a large energy jolt.
