Working Range

For maintenance planning, EP-YS-56M2-4 is considered as a compact low-power three-phase duty selection with vibration 1.8 mm/s. The useful engineering question is how that operating point behaves in small pumps, compact conveyors, agricultural auxiliaries and light machinery. Record the driven-machine load and output speed first, then check reference speed 1330 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-YS-56M2-4 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 compact gearboxes, couplings, pulleys and small chain drives inside the same scope so the machine does not inherit an interface assumption.

Process Fit

For this model, EP-YS-56M2-4 is considered as a compact low-power three-phase duty selection with rated output 90 W. The useful engineering question is how that operating point behaves in small pumps, compact conveyors, agricultural auxiliaries and light machinery. Record the driven-machine load and output speed first, then check rated current 0.67/0.39 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 compact gearboxes, couplings, pulleys and small chain drives connect to EP-YS-56M2-4 so the machine does not inherit an interface assumption.

Drive Package

At the documented operating point, EP-YS-56M2-4 is considered as a compact low-power three-phase duty selection with reference speed 1330 r/min. The useful engineering question is how that operating point behaves in small pumps, compact conveyors, agricultural auxiliaries and light machinery. Record the driven-machine load and output speed first, then check efficiency 58% against the actual supply and duty. A motor row becomes meaningful only when those values are attached to the machine it will run.

Vibration 1.8 mm/s 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 so the machine does not inherit an interface assumption.

Protection Strategy

On a new machine, EP-YS-56M2-4 is considered as a compact low-power three-phase duty selection with rated current 0.67/0.39 A. The useful engineering question is how that operating point behaves in small pumps, compact conveyors, agricultural auxiliaries and light machinery. Record the driven-machine load and output speed first, then check noise 65 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.

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 so the machine does not inherit an interface assumption.

Assembly Review

In a replacement project, EP-YS-56M2-4 is considered as a compact low-power three-phase duty selection with efficiency 58%. The useful engineering question is how that operating point behaves in small pumps, compact conveyors, agricultural auxiliaries and light machinery. Record the driven-machine load and output speed first, then check vibration 1.8 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.

The mechanical review should include compact gearboxes, couplings, pulleys and small chain drives. 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 so the machine does not inherit an interface assumption.

Keep compact gearboxes, couplings, pulleys and small chain drives inside the same scope before a replacement is ordered from memory.
