Matching the Exact Drive to Your Motor

Getting the perfect out of your operations means executing more than merely connecting a motor to a part of electrical device. You will even need a drive to work like an intermediary, moderating the power flow from the motor to the devices and supporting safer, more effectual results.

But how you can choose the right drive? How do you choose a drive, which aligns with the particular motor and particular application? Read on at CM Industry Supply Automation to learn more.

The terms Variable Speed Drive (VSD), Variable Frequency Drive (VFD) and Adjustable Speed Drive (ASD) all represent the same thing. This is an equipment, which controls the electric motor output, dictating the revolving speed, or torque, the motor produces.

Being able to change the motor speed offers lots of advantages which include:

  •     Better durability of parts
  •     Reduced operating prices as the motor does not require to be at complete power every time
  •     Cut down carbon footprint during functioning
  •     Reduced damage risk to the motor or other parts
  •     Control over direction of motor and torque output

What are Soft Starter Drives?

Soft starter drives are simpler set up as compare to VFD, ASD, or VSD, but it still uses some control over the connection. These drives usually implement a soft start, which means soft starter drive will slowly increase the motor output during start-up, cutting down the stress placed on the motor during this operation phase and rising its operation lifecycle.

Direct On Line (DOL) or Across the Line Drives

Direct On Line or Across the Line drives maintain a stable, uniform production from the motor. No control is there over different output level, and there is no speed variation, frequency or other function. This is an easier system. But it is even less efficient since the motor will be operating at complete capacity whenever it is turned on. Due to this the system parts may experience more deterioration over time, and the Carbon footprint of the system get rise too.

Rating alignment

Drives are usually rated based on their horsepower capability. However, when it comes to matching up the drive to the motor the story might be different. The drive makers will even provide power ratings (measured in volts), current ratings (measured in amps) and frequency ratings (measured in hertz). And for each metric there will be an input and output rating. The motor has to meet the input rating parameters, while the devices which is being powered have fall within the output rating parameters.

Constant or Variable Torque

Equipment that needs a constant torque load around all speeds – where the motor torque and the load torque should be the same during steady-state working such as cranes, lift drives, hoists, rotary and screw compressors.

Make the Best Choice and Optimize Your Operation

According to CM Industry Supply Automation, if you fail to match up the right drive with the right motor for your application you will experience the difficulty in your business. You may see that the motor is simply not able to perform the task as the essential output level cannot be transmitted to the devices. Or you may find that the set-up turned out overloaded and cuts out. Other issues linked with choosing the wrong drive for your motor remain high operational costs, damage to puts inside the system and a corrupt impact on our environmental setting.

Do your research and select the right drive among Lenze drive, Siemens drive, Keb drive, Danfoss drive, or Darwin Motion VFD with your motor combination and run your business as efficiently as possible.
