EP-FAB \u2014 Square Flange<\/h3>\n

Four-bolt square output flange. Standard mounting for servo motors with ISO square-flange interfaces. 20,000 hr life. Backlash P0 \u22641 arc-min.<\/p>\n

Choose when: square-flange mounting is standard in your machine, or when P0 \u22641 arc-min is required.<\/div>\n<\/div>\n

EP-FAD \u2014 Round Flange<\/h3>\n

Circular bolt-circle output flange. Direct bolt-on to rotary tables, actuator housings, and round-flange servo systems. 30,000 hr life. 10,000 rpm max input.<\/p>\n

Choose when: round-flange integration, high-speed input, or 30,000 hr service life is the priority.<\/div>\n<\/div>\n<\/div>\n
\n
\n

The EP-FAD uses the same profile-ground helical planetary gearset as the EP-FAB, but the output end carries a circular (round) flange<\/strong> with a bolt-circle pattern \u2014 the preferred interface for rotary table drives, direct-mount actuators, and machinery complying with ISO 9409 round-flange standards.<\/p>\n

The bearing and housing system is upgraded for 30,000 hours of service life<\/strong> \u2014 50% longer than the EP-FAB’s 20,000 hr \u2014 making the EP-FAD the right choice for continuous-duty high-speed axes where scheduled maintenance is difficult or costly.<\/p>\n

Note that the EP-FAD includes special gear ratios \u2014 i=16, 21, 31, 61, and 91<\/strong> \u2014 in addition to the standard series. These are available in select frame sizes and cover gaps not served by the standard 1-stage (4\u201310) and 2-stage (20\u2013100) ratio steps.<\/p>\n<\/div>\n

Motor Assembly Notes<\/h2>\n

\"EP-FAD<\/p>\n

EP-FAD clamp-ring adapter assembly and round-flange output dimensions<\/p>\n<\/div>\n

\n

Motor input assembly uses the same clamp-ring adapter system (C1\u2013C10) as the EP-FAB and EP-FABR \u2014 the eight-step assembly process is identical. Three considerations specific to the round-flange output:<\/p>\n

\n
\ud83d\udd18 Output Flange Bolt Pattern<\/div>\n

The round output flange uses a bolt-circle with thread holes on the face and a pilot bore (\u00d8D1) for centring. Verify the mating rotary table or actuator body matches the EP-FAD bolt-circle diameter (D8) and pitch (D9) for the chosen frame size before ordering.<\/p>\n<\/div>\n

\n
\ud83d\udcd0 Axial Force at Output Flange<\/div>\n

The round flange output does not carry radial shaft force \u2014 the axial force rating (F_ax) and bending moment (M\u2098\u2090\u2093) are the relevant load limits. For cantilevered loads, verify M\u2098\u2090\u2093_actual \u2264 M\u2098\u2090\u2093_rated at the output flange face.<\/p>\n<\/div>\n

\n
\ud83c\udf21\ufe0f High-Speed Thermal Check<\/div>\n

At input speeds above 6,000 rpm, verify that the mean torque \u00d7 input speed does not exceed the thermal power limit for the frame size. Continuous operation at max speed under full rated torque may require forced-air cooling for EP-FAD200 and EP-FAD255.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Frequently Asked Questions<\/h2>\n
\n
Q: Why is P0 grade not available for EP-FAD047 and EP-FAD064?<\/div>\n
The very small gear geometry in the 047 and 064 frames limits the planet gear count and planet gear size relative to the ring gear \u2014 the inherent geometric constraint means the minimum achievable backlash in 1-stage is approximately 2\u20133 arc-min rather than \u22641 arc-min. From EP-FAD090 upward, the larger gear geometry allows the tighter manufacturing tolerances needed for P0 grade. For applications requiring P0 in small frame sizes, the EP-FAB042 or EP-FAB060 square-flange series achieves P0 \u22641 arc-min and can be used with a round-flange adapter plate.<\/div>\n<\/div>\n
\n
Q: What are the special ratios (i=16, 21, 31, 61, 91) for, and why are they not in the standard series?<\/div>\n
Standard planetary gearbox ratios are constrained by the gear tooth count relationship: (ring teeth) = (sun teeth) + 2 \u00d7 (planet teeth). This limits available ratios to specific integer values. The special ratios 16, 21, 31, 61, and 91 are achieved through an alternative gear tooth count combination that requires a different planet gear count or a modified ring gear geometry \u2014 making them a separate product variant. They are specifically useful in semiconductor and FPD equipment where the substrate pitch or transport speed dictates an exact output speed that the standard ratio series cannot match without a fractional-ratio external reduction.<\/div>\n<\/div>\n
\n
Q: How does the 30,000-hour life compare to the EP-FAB, and what is the actual test basis?<\/div>\n
The 30,000-hour rating is a calculated L10 bearing life under the stated conditions: rated torque at 50% mean load, rated input speed, and standard operating temperature (\u221210\u00b0C to +90\u00b0C). It is 50% longer than the EP-FAB’s 20,000-hour rating, achieved through a combination of larger bearing bore sizes in the output section and a more favourable load-to-bearing-capacity ratio. In intermittent duty (S5) at \u226460% ED, or at loads below 50% of rated torque, actual service life will be significantly higher. The 30,000-hour figure is not a warranty but a design-basis service-life calculation per ISO 281.<\/div>\n<\/div>\n
\n
Q: Can I use the EP-FAD with a DDR (direct-drive) or torque motor instead of a standard servo?<\/div>\n
Yes, with the appropriate adapter. DDR and torque motors typically have large hollow-shaft outputs; the EP-FAD input uses the standard clamp-ring adapter (C1\u2013C10) which is designed for solid servo motor shafts. A custom adapter flange can be machined to bridge the DDR output flange to the EP-FAD input bore. This is a common configuration in FPD equipment where a DDR provides fast coarse rotation and the EP-FAD provides the final precision reduction. Contact Korea Ever-Power with the DDR motor model for adapter dimension verification before ordering.<\/div>\n<\/div>\n
\n
Q: What is the bending moment limit, and when does it apply?<\/div>\n
The bending moment limit M\u2098\u2090\u2093 applies when the output flange carries a cantilevered load \u2014 for example, when a rotary table platter is bolted to the output flange and the workpiece weight creates a moment about the flange face. If the cantilevered load mass (m) acts at a radius (r) from the flange centreline, then M_actual = m \u00d7 g \u00d7 r, and this must be less than M\u2098\u2090\u2093 for the selected frame. For EP-FAD047 (M\u2098\u2090\u2093 = 42.5 Nm), this limits cantilevered mass-radius products to approximately 4.3 kg\u00b7m. For EP-FAD255 (M\u2098\u2090\u2093 = 5,900 Nm), the limit is approximately 601 kg\u00b7m \u2014 suitable for large rotary table applications.<\/div>\n<\/div>\n

We specified EP-FAD090 with i=21 (special ratio) for our OLED exposure system’s theta axis. The standard i=20 gave a 0.5% speed error that accumulated over a 2,200 mm glass substrate \u2014 the EP-FAD021 eliminates that error entirely. After 18 months at 8,000 rpm on a 3-shift line, still within P1 backlash spec.<\/p>\n

“Switched from a European competitor to EP-FAD140 on our 5-axis rotary table line. Round flange bolts directly to our table housing \u2014 eliminated the 12 mm adapter plate height we had with the square-flange gearbox and reduced table runout by 8 arc-sec.”<\/p>\n

“Our wafer handler ran EP-FAD047 at 9,500 rpm input for 14 months straight. No thermal issues, no bearing noise, backlash still measures P1. The 30,000 hr life claim appears credible \u2014 our previous gearbox needed replacement at 18,000 hr.”<\/p>\n

“Used EP-FAD200 (i=31 special ratio) for a large glass panel robot. The ratio matched our transport pitch perfectly \u2014 no encoder correction factor needed. Lead time for special ratio was 4 weeks, slightly longer than standard, but worth it for the accuracy improvement.”<\/p>\n

“We run EP-FAD110 on our pharmaceutical capsule-filling carousel at 4,000 rpm continuous. The 30,000 hr design life means we plan one gearbox replacement over the machine’s full 15-year lifecycle \u2014 versus three replacements with the 20,000 hr units we used before. That’s significant downtime and cost savings.”<\/p>\n

“The round flange is a real differentiator. On our direct-drive rotary actuator, the EP-FAD255 bolts directly to the actuator housing face \u2014 no adapter, no alignment shimming. We eliminated 3 mm of stack height and two potential backlash stack-up contributors. The torsional rigidity at 1,006 Nm\/arc-min is the highest in this frame size category.”<\/p>\n
