Description
EP-Y2EJ Brake Motor
EP-Y2EJ-225M-4
EP-Y2EJ-225M-4: 45 kW, 1480 r/min. Ip54 electromagnetic brake three-phase asynchronous motors for stopping, positioning and anti-coast duties; configured with matched transmission components when required.

Working Range
In a replacement project, EP-Y2EJ-225M-4 is considered as a motor duty combined with controlled stopping or holding selection with efficiency 92.5%. The useful engineering question is how that operating point behaves in lifting, packaging, printing, transport and positioning machinery. 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.
Reference speed 1480 r/min 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 regional conformity work begins.
Process Fit
When the drive is assembled, EP-Y2EJ-225M-4 is considered as a motor duty combined with controlled stopping or holding selection with noise 90 dB(A). The useful engineering question is how that operating point behaves in lifting, packaging, printing, transport and positioning machinery. Record the driven-machine load and output speed first, then check rated output 45 kW 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 regional conformity work begins.
Drive Package
During technical review, EP-Y2EJ-225M-4 is considered as a motor duty combined with controlled stopping or holding selection with vibration 3.5 mm/s. The useful engineering question is how that operating point behaves in lifting, packaging, printing, transport and positioning machinery. Record the driven-machine load and output speed first, then check reference speed 1480 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.
The mechanical review should include gearboxes, couplings, brake controls, pulleys, sprockets and chains. 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 regional conformity work begins.
Protection Strategy
For an OEM buyer, EP-Y2EJ-225M-4 is considered as a motor duty combined with controlled stopping or holding selection with rated output 45 kW. The useful engineering question is how that operating point behaves in lifting, packaging, printing, transport and positioning machinery. Record the driven-machine load and output speed first, then check rated current 85 A 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-Y2EJ-225M-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 gearboxes, couplings, brake controls, pulleys, sprockets and chains inside the same scope before controls and guards are finalized. The selected row lists brake torque of 450 N·m and brake time of 0.80 s. Those values should be compared with the actual driven inertia and stopping function; a brake motor does not by itself define the machine safety system.
Assembly Review
At commissioning, EP-Y2EJ-225M-4 is considered as a motor duty combined with controlled stopping or holding selection with reference speed 1480 r/min. The useful engineering question is how that operating point behaves in lifting, packaging, printing, transport and positioning machinery. Record the driven-machine load and output speed first, then check efficiency 92.5% 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, brake controls, pulleys, sprockets and chains connect to EP-Y2EJ-225M-4 before controls and guards are finalized.
Export Project
Under steady production duty, EP-Y2EJ-225M-4 is considered as a motor duty combined with controlled stopping or holding selection with rated current 85 A. The useful engineering question is how that operating point behaves in lifting, packaging, printing, transport and positioning machinery. Record the driven-machine load and output speed first, then check noise 90 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 45 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.

45 kW
What speed is listed for EP-Y2EJ-225M-4?
1480 r/min
Which transmission parts can be reviewed with it?
Typical paired components include gearboxes, couplings, brake controls, pulleys, sprockets and chains. Final compatibility is checked from the machine drawing and duty.
Can this motor be used in any country?
No universal claim is made. Destination efficiency, marking and conformity requirements must be checked for the exact configuration.
What should I send for a replacement?
Send nameplate data plus shaft diameter and extension, key, foot or flange pattern, frame or shaft height, envelope and the driven connection.
What commissioning data is useful?
Record current, temperature, noise and vibration under a known load. The selected row lists 85 A, 90 dB(A) and 3.5 mm/s where documented, providing reference values for comparison rather than replacing a site baseline.
