Brushless DC (BLDC) Hub Motors Custom

Brushless DC (BLDC) Hub Motors

-- Stadig och pålitlig tillverkare --

The Standard for Modern Hub Drive Technology

The brushless DC (BLDC) hub motor has revolutionized the light electric vehicle (LEV) market, offering a level of efficiency, reliability, and power density that was once thought impossible. By eliminating the friction-prone brushes of traditional DC motors, BLDC technology provides a maintenance-free life cycle and a significantly higher power-to-weight ratio. As a specialized manufacturer established in 1995, we have spent nearly three decades perfecting the design of these motors. From our early days as "Hengtai Motor" to our current global presence, our focus has always been on the precision casting and electromechanical innovation required to make a hub motor that doesn't just work, but lasts for tens of thousands of miles.

At the heart of our BLDC hub motors is a sophisticated internal architecture. We utilize high-grade Neodymium (NdFeB) magnets and high-density copper windings to ensure maximum electromagnetic flux. Our 9,000sqm manufacturing campus includes dedicated vacuum-impregnation lines for our windings, ensuring they are protected against moisture and vibration. This attention to detail is what allows our motors to achieve efficiency ratings exceeding 85%, extending the range of any vehicle they are installed on. Whether it is a 250W city commuter or a 1000W high-torque cargo motor, the fundamental principles of quality remain the same: superior materials and precision manufacturing.

Innovation is part of our DNA, as evidenced by our Patented Nylon-Steel Gear design found in our geared BLDC hub units. This hybrid gearing provides the quiet, smooth ride of nylon with the rugged durability of steel, effectively solving the "weak point" found in many competitive geared motors. We believe in our engineering so much that we once launched a 30,000-mile guarantee program—a test that our motors didn't just meet, but many units exceeded by reaching the 50,000-mile mark. For B2B partners, this means a product that has been proven in the real world and is backed by an ISO 9001 quality management system.

Wide-Ranging Mobility Applications

Our BLDC hub motors are the "workhorse" of the light electric mobility world. Their primary application is in the Electric Bicycle (E-Bike) market, where they provide silent, intuitive pedal assistance. They are also widely used in Electric Scooters and personal mobility devices where space is at a premium and reliability is non-negotiable. Because the motor is integrated directly into the wheel, there are no chains or belts to maintain, making them the perfect choice for consumer-facing vehicles that need to remain "maintenance-free" for the duration of their lifespan.

  • City and Commuter E-bikes (250W-350W versions).
  • Electric Cargo Bikes requiring heavy-load geared hub motors.
  • Foldable Electric Scooters for the "last-mile" urban commute.
  • Electric Wheelchairs and medical mobility aids.
  • Lightweight Electric Delivery Trikes for couriers.

The Engineering Advantage of Brushless Systems

The core advantage of our BLDC hub motors lies in the Integration of Material Science and Mechanical Engineering. By using our 500-ton die-casting machines to create aluminum-magnesium alloy housings, we solve the problem of weight while providing a natural heat sink for the internal electronics. This material choice, combined with our precision CNC processing, ensures that the motor remains concentric and balanced, reducing noise and vibration even at high speeds. Our silent operation is a key selling point for high-end LEV brands.

Furthermore, our durability story is unmatched in the industry. The fact that 50 of our motors surpassed 50,000 miles in field testing is a testament to our proprietary internal designs. From the quality of the silicon steel to the precision of the micro-arc oxidation surface treatment, every element is designed to resist the wear and tear of daily use. We don't just assemble motors; we engineer them from the ground up to be the most reliable component of your vehicle. Backed by 30 years of history, HENTACH is the name that global brands trust for their high-performance hub drive needs.

Global Commerce and Logistics

We provide seamless B2B trade services, supporting manufacturers from the prototype phase to mass production. We accept T/T, L/C, and OA (for long-term partners) and provide full logistical support from our base in Ningbo. Our export-grade packaging ensures that motors arrive in perfect condition, regardless of the shipping duration.

  • MOQ: 100 units for standard models; custom orders negotiable.
  • Certification: CE, RoHS, EN15194 compliant.
  • Customization: Full OEM color and logo options available.
  • Shipping: Sea, Air, and Express options with full tracking.
  • Q: What is the difference between a geared and a gearless BLDC hub motor?
  • A: Geared motors use an internal planetary gear set to provide higher torque at lower speeds, making them ideal for hills and heavy loads. Gearless (Direct Drive) motors are simpler and can reach higher top speeds but are generally heavier.
  • Q: Can these motors handle riding in heavy rain?
  • A: Yes, our motors are rated IP65/IP66, meaning they are sealed against dust and water ingress. We use specialized seals and waterproof connectors to ensure reliability in wet weather.
  • Q: Do you offer different winding options for speed or torque?
  • A: We do. We can customize the "kV" (RPM per Volt) of the motor by adjusting the number of turns in the winding to meet your specific performance profile.
