Market Trends Insights

Electric scooter hub motors represent a specific type of electric hub motor, which has been previously utilized in cars and industrial vehicles. Now, these motors are increasingly being incorporated into personal electric vehicles like electric scooters.

Renowned for their permanent magnet synchronous design, these motors are often referred to as Brushless DC motors. Unlike traditional DC motors, they lack intricate carbon brush systems and, as a result, require an electronic inverter for operation. They have higher efficiency and power capabilities, making them particularly effective for producing significant torque even in smaller devices.

As of 2022, the worldwide market for two-wheeler hub motors was valued at approximately USD 10.34 billion. Forecasts suggest a growth trajectory with a compound annual growth rate (CAGR) of 12.3% from 2023 to 2030. Countries like China and the U.S. are encouraging the use of e-scooters and e-bikes through subsidies, promoting eco-friendly transportation methods. These measures are expected to boost the market share of electric two-wheeler motors.

Three Basic Concepts for Electric Scooter Hub Motor

Rated Power | Rated power, often referred to as continuous power, represents the level of power that an electric scooter motor can consistently use over time without the risk of overheating or damage. The measurement of power in watts can vary in precision, and different manufacturers may have their own methods of calculating motor wattage. For instance, two motors rated at 500W each may not actually deliver identical mechanical power, indicating that motors with the same rated continuous power can exhibit varied performance levels.

Maximum Power | Maximum power usage is the measure of the maximum power that the electric scooter hub motor can utilize in short, intense bursts. Typically, a higher maximum power rating equates to quicker acceleration and more efficient hill climbing capabilities in electric scooters, making this a crucial figure to consider. Typically, the levels your scooter consumes on the road are its continuous power. The actual value is mainly 30% to 90% of the peak figure. On average, the continuous power of most scooters is 57% of the peak value.

Motor Torque | Motor torque refers to the rotational force generated by the electric scooter hub motor, which is responsible for turning the wheels and propelling the scooter forward. This force is quantified in Newton meters (NM) or foot-pounds. While watts indicate the electric motor’s input capacity – the power it can draw – torque is a measure of the motor’s output, or the actual power it produces.

Comparisons of Different Kinds of Electric Scooter Motors

Feature/Aspect Brush Motor Brushless Motor (BLDC)
Introduction One of the oldest technologies, dating back to the early 1800s. Recent technology, more advanced compared to brushed motors.
Operation Mechanically operates through graphite/carbon brushes. Operates electronically with alternating power in motor coils.
Pros Low construction cost Better power to weight ratio
Simple controller More energy efficient
Reduces the price of the scooter It does not overheat often
Cons Older technology More expensive
Wears out with time It causes some power loss
Production in this era is limited  
Feature/Aspect Geared Hub Motor Gearless Hub Motor 
Introduction Small motor inside a casing with external gears. Simple structure with two key parts: rotor and stator.
Operation Power is transferred to wheels through gears. Axle rotation driven by electromagnets.
Pros Long range Higher maximum speeds
Power output is high Better hill-climbing angle
Maintains good speed Maintains speed efficiently
Cons Experiences more wear and tear Overall efficiency is low
Short lifespan It makes the scooter heavy as the motor size is larger
Requires repairs often
