Energy-Saving DC Motor Technology

The Efficiency Mandate: Pioneering Energy-Saving DC Power
In the world of battery-powered mobility, energy is the most precious resource. At HENTACH, formerly known as Hengtai Motor, our Energy-Saving DC Motor Technology is the result of three decades of optimizing the relationship between magnetic flux and electrical consumption. Since 1995, our 9,000-square-meter facility has been dedicated to the pursuit of the "High-Efficiency Curve"—a motor that delivers maximum torque with minimum battery drain. We understand that for our B2B partners, an extra 5% of efficiency isn't just a technical spec; it’s an extra 10 miles of range for their customers or a smaller, cheaper battery pack for their vehicle. Our electromechanical innovation is focused on eliminating the three "enemies" of energy: heat, friction, and electromagnetic interference.
The foundation of our energy-saving technology is the use of ultra-thin 0.35mm silicon steel laminations in the motor core. By reducing the thickness of the laminations, we significantly lower eddy current losses, which are the primary cause of heat buildup and energy waste in high-speed motors. Combined with our high-fill-factor copper windings, we achieve peak efficiency ratings that consistently exceed 88%. These results are not just for the lab; our motors are proven to exceed a 50,000-mile durability benchmark in the field, maintaining their efficiency even after years of use. This longevity is a hallmark of the "Hengtai" legacy, ensuring that the energy-saving benefits last the entire life of the vehicle. Our in-house 500-ton die-casting also plays a role, providing a housing that acts as a precision heat sink, preventing efficiency decay as the motor warms up during long hauls.
Furthermore, our energy-saving motors utilize our patented nylon-steel hybrid gears. In traditional metal gearboxes, significant energy is lost to mechanical drag and the churning of heavy lubricants. Our hybrid gearsets are self-lubricating and offer a much lower coefficient of friction, reclaiming up to 10% of the energy typically lost in the transmission. This holistic approach—optimizing both the electrical and mechanical systems—is what sets HENTACH apart. Our ISO 9001 certified campus uses high-precision dynamometers to verify the efficiency of every motor batch before shipping. For B2B partners looking to lead the "Green Revolution," HENTACH provides the professional-grade technology needed to make every watt count. We are committed to engineering a more sustainable and efficient world.

Applications for Long-Range Mobility
Energy-saving motors are the primary choice for Long-Range Touring E-bikes, where riders need the confidence to tackle 100km+ journeys on a single charge. They are also essential for Solar-Powered Vehicles and high-altitude drones, where energy harvesting is slow and every milliwatt must be preserved for flight. In the commercial sector, our efficiency-first motors power Last-Mile Delivery Fleets, allowing vehicles to complete their entire daily route without needing a midday recharge. The 30-year legacy of HENTACH ensures that our motors provide the most efficient path from battery to wheel, regardless of the terrain or load. We provide the "Invisible Range Extender" for your electric vehicle.
- Touring and Trekking E-bikes with long-range targets.
- Commercial Cargo Scooters for 8-hour delivery shifts.
- Lightweight Folding E-scooters for multi-modal transit.
- Solar-assisted vehicles and marine propulsion.
- Precision Laboratory equipment requiring low heat emission.
The Advantage of "Cool-Run" Technology
The primary advantage of HENTACH energy-saving technology is Thermal Longevity. Efficiency and heat are inversely related; a motor that wastes 20% of its energy is essentially an electric heater that degrades its own internal components. By pushing our efficiency to 88%+, our motors run significantly cooler than the competition. This protects the Hall sensors, the winding insulation, and the magnets from thermal degradation, which is why our motors are proven to reach 50,000 miles. This is a direct result of our 30-year legacy of electromechanical heritage. Our 500-ton die-casting ensures that any heat that is generated is quickly moved to the outer surface, maintaining the motor in its peak efficiency "sweet spot."
Furthermore, our System-Level Optimization means we can match our motors with high-efficiency sine-wave controllers to minimize switching losses. We provide B2B partners with complete efficiency maps, allowing your engineers to program the vehicle’s power management for maximum performance. Our ISO 9001 certified facility uses computerized winding machines to ensure that every motor is a perfect, low-resistance replica of the master design. Choosing HENTACH means you are partnering with a manufacturer that prioritizes professional-grade efficiency over short-term cost-cutting. We provide the technical depth and industrial scale to make your energy-saving goals a reality. Drive further, waste less, and lead the market with HENTACH.
