Operating Point

Under steady production duty, EP-YD-160L-4/2 is considered as a discrete pole-changing speed operation selection with rated current 22.3/28.8 A. The useful engineering question is how that operating point behaves in machine tools, textile machinery, mining equipment and stepped-speed drives. Record the driven-machine load and output speed first, then check noise 95 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.

Rated output 11/14 kw 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. The two documented speeds are discrete operating points created by the winding/pole arrangement, which is a different design decision from continuous VFD speed control.

Machine Fit

Before the drawing is released, EP-YD-160L-4/2 is considered as a discrete pole-changing speed operation selection with efficiency 87/82%. The useful engineering question is how that operating point behaves in machine tools, textile machinery, mining equipment and stepped-speed drives. Record the driven-machine load and output speed first, then check vibration 2.8 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.

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

When a gearbox is added, EP-YD-160L-4/2 is considered as a discrete pole-changing speed operation selection with noise 95 dB(A). The useful engineering question is how that operating point behaves in machine tools, textile machinery, mining equipment and stepped-speed drives. Record the driven-machine load and output speed first, then check rated output 11/14 kW 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 gearboxes, couplings, pulleys, shafts and machine transmissions. 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.

Control Review

For maintenance planning, EP-YD-160L-4/2 is considered as a discrete pole-changing speed operation selection with vibration 2.8 mm/s. The useful engineering question is how that operating point behaves in machine tools, textile machinery, mining equipment and stepped-speed drives. Record the driven-machine load and output speed first, then check reference speed 1460/2920 r/min 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-YD-160L-4/2 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 gearboxes, couplings, pulleys, shafts and machine transmissions inside the same scope before regional conformity work begins. The two documented speeds are discrete operating points created by the winding/pole arrangement, which is a different design decision from continuous VFD speed control.

Mounting Detail

For this model, EP-YD-160L-4/2 is considered as a discrete pole-changing speed operation selection with rated output 11/14 kW. The useful engineering question is how that operating point behaves in machine tools, textile machinery, mining equipment and stepped-speed drives. Record the driven-machine load and output speed first, then check rated current 22.3/28.8 A 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 gearboxes, couplings, pulleys, shafts and machine transmissions connect to EP-YD-160L-4/2 before regional conformity work begins.
