The brushed hub motor is a classic and reliable technology that has been powering electric bikes for many years. Despite the emergence of brushless motors, the brushed hub motor remains a popular choice due to its simplicity, durability, and cost-effectiveness. In this blog, we will explore the brushed hub motor, its advantages, and its applications in the world of electric bikes.
To understand the advantages of the brushed hub motor, it's essential to know how it operates. The brushed hub motor consists of a central rotor surrounded by copper wire windings and permanent magnets. When an electric current flows through the windings, it generates a magnetic field that interacts with the magnets, causing the rotor to spin. The brush system transfers electrical current to the windings, hence the name "brushed" motor.
Simplicity and Cost-Effectiveness: Brushed hub motors are relatively simple in design, resulting in lower manufacturing costs. This cost-effectiveness makes them an attractive option for budget-friendly electric bikes.
High Torque at Low Speeds: Brushed hub motors deliver high torque even at low speeds, making them well-suited for electric bikes designed for climbing hills or carrying heavier loads.
Durability and Longevity: The absence of complex electronics in brushed hub motors contributes to their durability and longevity. With fewer components to fail, these motors often withstand the test of time with minimal maintenance.
Easy Repairs and DIY Maintenance: If repairs are necessary, brushed hub motors are relatively easy to fix, making them a practical choice for DIY enthusiasts.
Affordable E-Bikes: Brushed hub motors are commonly used in entry-level or budget-friendly electric bikes, allowing manufacturers to offer affordable options to a wider range of consumers.
Hill-Climbing and Cargo E-Bikes: The high torque output of brushed hub motors makes them suitable for hill-climbing e-bikes and cargo e-bikes that require extra power to handle challenging terrains and heavy loads.
Conversion Kits: Brushed hub motors are also popular choices for e-bike conversion kits, allowing cyclists to transform their traditional bikes into electric bikes without breaking the bank.
The brushed hub motor continues to be a reliable and cost-effective option for electric bikes, offering simplicity, durability, and high torque performance. Its applications range from affordable e-bikes to hill-climbing and cargo e-bikes, as well as conversion kits for existing bicycles. While newer technologies like brushless wheel hub motor have gained popularity, the brushed hub motor remains a practical choice for those seeking an efficient and budget-friendly electric bike solution.
