Operating Point

For this model, EP-YVF2-280M-4 is considered as a variable-frequency operation with independent ventilation selection with rated output 90 kW. The useful engineering question is how that operating point behaves in conveyors, pumps, fans, mixers and process lines requiring speed control. Record the driven-machine load and output speed first, then check rated current 166.9 A against the actual supply and duty. A motor row becomes meaningful only when those values are attached to the machine it will run.

Noise 99 db(a) is a useful catalog reference, but commissioning should create a site baseline under a known load. Note current, temperature and visible vibration at the same time. If a gearbox or chain stage is part of the drive, record its condition too before controls and guards are finalized.

Machine Fit

At the documented operating point, EP-YVF2-280M-4 is considered as a variable-frequency operation with independent ventilation selection with reference speed Variable speed; 50 Hz base. The useful engineering question is how that operating point behaves in conveyors, pumps, fans, mixers and process lines requiring speed control. Record the driven-machine load and output speed first, then check efficiency not specified on this selected row against the actual supply and duty. A motor row becomes meaningful only when those values are attached to the machine it will run.

Destination country belongs in the technical record. A motor that is mechanically suitable may still sit inside a different efficiency, marking or conformity scope in the United States, European Union, Japan, Brazil, Mexico or another market. Separate that regulatory check from the machine calculation before controls and guards are finalized.

Torque Path

On a new machine, EP-YVF2-280M-4 is considered as a variable-frequency operation with independent ventilation selection with rated current 166.9 A. The useful engineering question is how that operating point behaves in conveyors, pumps, fans, mixers and process lines requiring speed control. Record the driven-machine load and output speed first, then check noise 99 dB(A) against the actual supply and duty. A motor row becomes meaningful only when those values are attached to the machine it will run.

The mechanical review should include VFDs, gearboxes, couplings, shafts and pulley systems. In this model size, do not assume that matching power guarantees a matching shaft or flange. Confirm the drawing, bore, key, shaft engagement and guard space before controls and guards are finalized. For variable-frequency work, the minimum continuous speed and the independent ventilation arrangement deserve explicit review because cooling no longer follows shaft speed in the same way as a self-ventilated fixed-speed motor.

Control Review

In a replacement project, EP-YVF2-280M-4 is considered as a variable-frequency operation with independent ventilation selection with efficiency not specified on this selected row. The useful engineering question is how that operating point behaves in conveyors, pumps, fans, mixers and process lines requiring speed control. Record the driven-machine load and output speed first, then check vibration 3.5 mm/s against the actual supply and duty. A motor row becomes meaningful only when those values are attached to the machine it will run.

For purchasing, state whether EP-YVF2-280M-4 is a new OEM selection, an interchange or part of an efficiency retrofit. That context decides which dimensions are fixed and which can change. Keep VFDs, gearboxes, couplings, shafts and pulley systems inside the same scope before regional conformity work begins. For variable-frequency work, the minimum continuous speed and the independent ventilation arrangement deserve explicit review because cooling no longer follows shaft speed in the same way as a self-ventilated fixed-speed motor.

Mounting Detail

When the drive is assembled, EP-YVF2-280M-4 is considered as a variable-frequency operation with independent ventilation selection with noise 99 dB(A). The useful engineering question is how that operating point behaves in conveyors, pumps, fans, mixers and process lines requiring speed control. Record the driven-machine load and output speed first, then check rated output 90 kW against the actual supply and duty. A motor row becomes meaningful only when those values are attached to the machine it will run.

If the machine speed is created through reduction, calculate the complete ratio from motor shaft to driven shaft. A gearbox, sprocket or pulley can change both speed and shaft loading. The drawing should show where VFDs, gearboxes, couplings, shafts and pulley systems connect to EP-YVF2-280M-4 before regional conformity work begins.
