What do Benshaw Motor Control Products Do?

Benshaw is a pioneer in providing a comprehensive range of motor control solutions, especially in the realm of soft starters. Their products are designed to cater to a myriad of applications, from basic to severe duty requirements.

Benshaw Low Voltage Soft Starters: These soft starters are known for their mission-critical reliability, patented soft start technology, integral digital protection, and metering. They are ideal for a wide range of basic soft start applications. Advanced models, such as the EMX4 Series, come with "Smart Card" flexibility, offering added protection for heavy-duty applications. For severe duty applications, Benshaw's MX3 motor control technology, like the RB3 Series, stands out.

  • CSXi Series Compact Soft Starter: Compact, protected chassis motor control designed for standard-duty soft start applications.
  • EMX4 Series Protected Chassis Soft Starters: Features advanced "Smart Card" technology tailored for industry-specific, heavy/standard-duty soft start applications.
  • RB2 Series Open Chassis Soft Starters: Incorporates MX2 motor control technology with an integral bypass, suitable for severe duty soft start applications.
  • RB3 Series Open Chassis Soft Starters: Advanced MX3 technology with an integral bypass, designed for severe duty soft start applications.

Control Concepts has over 30 years of experience in Benshaw repair, service, and support. 

Benshaw Repair

Drives and soft starters, especially those from Benshaw, are typically reliable devices. Regular maintenance can mitigate many issues, but challenges like loose connections, programming glitches, or power semiconductor failures can arise.

When you are experiencing issues with a Benshaw product, our team can help troubleshoot the application. Most often the trouble is due to outside conditions rather than a faulty drive. If the equipment is the problem, we can provide fast and efficient upgrades and retrofits.

Common Drive Failures

  • Drive doesn’t run the motor
  • Drive keeps blowing fuses or tripping breakers
  • Loose connections
  • Non-functional cooling fans
  • Software or programming problems
  • Circuit board failure

Circuit board failure is the least common reason for drive failures. The most common fault that shuts down a drive is an over-current fault, of which there are 20-30 causes. We start with the dynamics of the motor and move on from there.

The Control Concepts Repair Process

Our repair process begins with a thorough inspection of the motor drive and terminals. We conduct comprehensive tests before powering the drive unit to prevent further damage. Once powered, we perform various tests to ensure the drive's functionality. We check the motor drive and terminals for substandard connections which can be caused by anything from heat cycles and mechanical vibration to reusing or over-tightening torque screws.

We conduct diode and IGBT tests on the input/output power sections before applying power to the drive unit. This is to protect against further damage from a short.

We power up the unit and perform amp readings and output frequency tests, slowly increasing the voltage until the rated input voltage of the drive is reached.

If everything functions properly, we use the drive to run a motor through basic jog functions after backing up existing programs. If the motor does not run, we check the output voltages and current ratings going to the motor to check the drive function for motor rotation.

Most drive failures can be avoided through preventative maintenance, such as:

  • Keep the drive free of dust
  • Ensure proper ventilation to prevent overheating
  • Keep everything dry and protected from moisture
