Motorredutor de aço com acionamento central EP-SYF-3M — Opção ultralenta de seis polos
EP-SYF-3M Center-Drive Steel Gear Motor — Product Overview
Maximum Efficiency, Maximum Torque, Integrated Motor
The EP-SYF-3M is the flagship center-drive gear motor in Korea Ever-Power’s irrigation range — the only product that combines 90% steel-gear efficiency, 1,130 Nm torque capacity, and a factory-integrated AC motor in a single turnkey unit. It delivers the energy savings and torque advantages of the EP-SYF-3 steel gearbox without requiring separate motor sourcing, coupler installation, or alignment verification. Bolt it to the tower frame, connect three-phase power, attach the driveline, and irrigate.
The Only Gear Motor with a 6-Pole Option
Every other Korea Ever-Power irrigation gear motor uses standard 4-pole motors (1,740 rpm at 60 Hz). The EP-SYF-3M offers an exclusive fourth variant — the EP-SYF-3M-40-6P — equipped with a 6-pole motor that runs at approximately 1,160 rpm. Combined with the 40 : 1 ratio, this produces just 28 rpm output: the slowest available output speed in Korea Ever-Power’s entire irrigation catalog. This ultra-slow mode enables precision low-application-rate irrigation for arid-climate water conservation, drip-supplement pivot systems, and chemigation applications where uniform, slow distribution is critical.
Ratio-Matched Motor Selection
Korea Ever-Power pairs each ratio with an optimally sized motor: 1½ HP for the 20 : 1 fast-advance ratio, 1 HP for the 30 : 1 standard ratio, ¾ HP for the 40 : 1 standard 4-pole variant, and ½ HP for the 6-pole ultra-slow variant. This precision matching means every motor operates at its most efficient load point — no oversizing waste, no undersizing risk.

Exclusive 6-Pole Motor Option — 28 RPM Ultra-Slow Precision Irrigation
The EP-SYF-3M-40-6P is available only in the EP-SYF-3M range — no other Korea Ever-Power irrigation gear motor offers a 6-pole configuration. Understanding when 28 rpm matters clarifies this variant’s unique value:
4-Pole Standard: 43 rpm
EP-SYF-3M-40-4P — ¾ HP motor
Standard tower advance speed for medium-span pivots. Suitable for most grain, corn, and vegetable irrigation where moderate water application rates match crop requirements. The 4-pole motor at 1,740 rpm produces the industry-standard 43 rpm output through the 40 : 1 ratio.
6-Pole Ultra-Slow: 28 rpm ★
EP-SYF-3M-40-6P — ½ HP motor
35% slower tower advance for precision low-rate irrigation. The 6-pole motor runs at ~1,160 rpm, producing 28 rpm through the same 40 : 1 ratio. Essential for arid-climate water conservation, chemigation uniformity, and drip-supplement pivot operation where slow, even distribution prevents runoff and maximizes absorption.
The Highest-Torque Gear Motor in the Irrigation Range
1,130 Nm + Integrated Motor = Turnkey Heavy-Duty
The EP-SYF-2M worm gear motor delivers 510 Nm. The EP-SYF-3M delivers 1,130 Nm — 2.2× more torque from an integrated unit that is ready to install. For irrigation companies building heavy-duty pivot systems with long spans and heavy towers, the EP-SYF-3M eliminates both the torque limitation of worm-gear motors and the installation complexity of separate gearbox-and-motor assemblies. One unit, one shipment, one installation step.
90% Efficiency Carries Through to the Motor
The integrated motor is factory-matched to the steel gearbox’s efficiency characteristics. Because only 10% of input power is lost in the gear mesh (versus 40–60% in worm gear motors), the EP-SYF-3M’s motor can be smaller for the same output performance. Smaller motors draw less current, generate less heat, and require less electrical infrastructure. The 2.3 AMP full-load draw at rated voltage is identical to the worm-gear EP-SYF-2M — but the EP-SYF-3M delivers 2.2× more output torque from that same current.
Four Motor-Ratio Combinations
The EP-SYF-3M offers four variants where the EP-SYF-2M worm motor offers six. The trade-off is deliberate: the steel gear architecture covers the 20 : 1 to 40 : 1 range where heavy-duty performance matters most, and adds the exclusive 6-pole variant that no worm-gear motor can match. For ratios above 40 : 1 (50, 58, 60 : 1), the worm-gear EP-SYF-2M remains the appropriate choice.

Cenários de aplicação em campo
Commercial Long-Span Pivot Systems
Large commercial pivots with 400+ meter spans and heavy galvanized steel towers are the EP-SYF-3M’s primary market. The 1,130 Nm torque handles the driveline loads that long outermost spans generate, and the 90% efficiency reduces the electricity cost of running these large systems thousands of hours per season. The pre-integrated motor eliminates the motor-selection guesswork that large-scale irrigation companies face when specifying separate gearboxes and motors for global deployment.
Arid-Climate Precision Irrigation (6-Pole)
In water-scarce regions like Saudi Arabia, Central Asia, and Australia’s interior, every drop of irrigation water must be absorbed by the soil rather than lost to runoff. The EP-SYF-3M-40-6P’s 28 rpm output moves the pivot arm 35% slower than the standard 43 rpm, giving the soil more time to absorb water before the next sprinkler pass. This ultra-slow mode reduces surface runoff, improves water use efficiency, and enables lower application rates that match the soil’s infiltration capacity.
Chemigation & Fertigation Applications
Pivot systems that inject chemicals or liquid fertilizer through the sprinkler heads require uniform, controlled application rates. The 6-pole EP-SYF-3M-40-6P’s 28 rpm produces the slowest, most uniform tower advance of any Korea Ever-Power gear motor, minimizing the application-rate variability that causes chemical hot-spots and under-treated zones. For farms applying expensive crop protection chemicals through the pivot, this precision directly improves chemical efficacy and reduces waste.
Why Choose the EP-SYF-3M
Exclusive 6-Pole 28 RPM
The slowest center-drive output in Korea Ever-Power’s catalog. No VFD required — mechanical 6-pole reduction provides ultra-slow precision for water-conserving and chemigation applications.
90% Efficiency + 1,130 Nm
The only gear motor that combines maximum efficiency with maximum torque in a factory-integrated package. Turnkey heavy-duty installation without separate motor sourcing or coupler alignment.
Tensão dupla 460/380V
Global grid compatibility. Moisture-sealed electrics, Class F insulation, and automatic thermal protection for unattended outdoor irrigation duty in any climate.
Instalação e manutenção
