General purpose or inverter-duty electric motor?
How to choose a general purpose motor vs. an inverter-duty motorGeneral purpose electric motors have been around for many years. They are the workhorse of almost every industry. An inverter-duty motor is a much newer concept that was necessary as general purpose motors began to be driven by variable frequency drives (VFDs or inverters). An inverter-duty motor can withstand the higher voltage spikes produced by all VFDs (amplified at longer cable lengths) and can run at very slow speeds without overheating. This performance comes at a cost: inverter-duty motors can be much more expensive than general purpose motors. Guidelines for choosing an Ironhorse general
purpose motor vs. an inverter-duty motor are available below. If
your application falls within the guidelines, there is no
need to apply an inverter-duty motor.
In summary, general purpose motors can be run with drives in many applications; however inverter-duty motors are designed to handle much lower speeds without overheating and they are capable of withstanding higher voltage spikes without their insulation failing. With the increased performance comes an increase in cost. This additional cost can be worth it if you need greater performance. |
