General purpose motors have been around for many years. They are the workhorse of almost every industry. An inverter duty motor can withstand the higher voltage spikes produced by all . Industrial electric motors from Baldor are available for most general purpose applications and processes.
However, some AC Variable Speed applications require constant torque at zero speed.
Aproval are avalable for Class I (Gas) and or Class II (Dust) hazardous enviroments when operated on adjustable speed (PWM inverter type) .
The answer is, in many cases, a standard duty AC motor will work just fine, although .
Inverters were originally sold to be used with standard motors , but an increasing failure rate for inverter-fed motors led to the introduction of motors for inverter duty . CT or 10:1VT Ex: Standard motor running half speed . NEMA Frame Inverter-Duty AC Motors. Available Marathon inverter - duty and vector-duty induction motors are organized here by horsepower rating. These motors are performance-matched for use with DURAPULSE or GS series AC drives, and are designed to handle much lower speeds without overheating and can withstand the voltage spikes typically . INVERTER - DUTY (also sometimes listed as inverter ready) means even more extras are built in.
All the inverter-ready items are there. Washdown Duty Premium Efficient. If you follow these guidelines, you can avoid more than is necessary.
Electronic adjustable speed drives, known as variable frequency drives (VFD), used to be marketed as “usable with any standard motor. Inverter Duty and Vector Duty Motors 23 4and 5Volts.
However, premature failures of motor insulation systems began to occur as fast-switching, pulse-width- modulated (PWM) VFDs were introduced. The switching rates of modern power . Obtain information from drive and motor manufacturers about inverter rise times and cable length effects, and use this information to evaluate the ability of existing motors to withstand drive-induced voltage stresses. VFDs are used in applications ranging from small appliances to large compressors.
IEC Frames FDL112− DL2Family. Specifically designed for operation with. Typical uses include, material handling, machine tools, conveyors, crane and hoist, metal processing, test stands, pumps, .
