A prominent transportation manufacturer in the United States aimed to upgrade its electric bicycle (e-bike) fleet to provide more efficient, quieter, and long-lasting products for urban commuters. The company needed a solution that could balance high performance with low maintenance requirements. After researching various motor options, they chose to work with BG Motor, a leading supplier of high-performance brushless DC motors. The customer specifically required a 48V DC brushless motor that offered high efficiency, low noise, long service life, effective heat dissipation, and high safety standards.
The customer faced several challenges that needed to be addressed:
Efficiency and Performance:The e-bikes required a motor that could provide consistent power with minimal energy loss, ensuring long battery life and reliable performance on various terrains.
Noise Control:Since the target market was urban commuters, the motor needed to operate quietly to avoid disturbing riders, especially during long rides in residential areas.
Durability:The motor needed to be durable enough to withstand the harsh conditions of daily use, including exposure to rain, dust, and occasional shocks from uneven road surfaces.
Effective Cooling:The motor needed a robust cooling system to prevent overheating, especially during prolonged use in warmer climates.
Safety:The motor had to meet international safety standards to ensure the reliability of the e-bike and reduce the risk of accidents due to motor failures.
BG Motor provided a 48V brushless DC motor with the following key features tailored to meet the customer’s requirements:
High EfficiencyThe motor was designed to maximize energy conversion with minimal heat loss, achieving an efficiency rate of over 85%. This high efficiency translated into longer battery life for the e-bikes, allowing riders to travel greater distances on a single charge.
Low Noise and Quiet OperationThe brushless design eliminated the need for brushes and commutators, reducing friction and, consequently, the noise generated during operation. This resulted in a whisper-quiet ride, which was essential for urban commuting in residential areas.
Long Service LifeThe use of premium materials and advanced engineering ensured that the motor would last for years with minimal wear. The brushless design also minimized mechanical wear and tear, significantly extending the motor's lifespan.
Effective Heat DissipationThe motor was equipped with a specialized cooling system, including high-quality heat dissipation materials and a well-designed structure to ensure optimal cooling. The efficient heat management system allowed the motor to maintain stable performance even during extended use, preventing overheating in hot climates or during uphill rides.
Enhanced Safety FeaturesThe motor incorporated overcurrent protection and overvoltage protection systems to prevent damage under extreme conditions. Additionally, the motor was designed to comply with international safety certifications, ensuring it met the stringent safety standards required by US transportation regulations.
BG Motor provided comprehensive after-sales support to ensure the customer’s e-bike fleet continued to perform optimally over time:
1、Warranty:The motors came with a2-year warranty covering any manufacturing defects or performance issues. This provided the customer with peace of mind and ensured long-term reliability.
2、Technical Support:BG Motor’s expert technical team was available for consultation, offering assistance with installation, troubleshooting, and optimization of the motor system. This ensured that any potential issues could be quickly addressed.
3、Replacement Parts:BG Motor offered a fast and efficient supply of replacement parts, minimizing downtime in the event of any component failure. The availability of parts ensured that the customer could maintain their fleet with minimal disruption.
4、Performance Monitoring:BG Motor implemented performance monitoring solutions that allowed the customer to track the health of the motors in real-time. This proactive approach enabled the customer to anticipate any issues and perform necessary maintenance before any failure occurred.
The collaboration between BG Motor and the US transportation manufacturer resulted in the successful development of an electric bicycle fleet that met all the performance, safety, and comfort requirements for urban commuters. BG Motor’s 48V brushless DC motor proved to be the ideal solution, offering high efficiency, low noise, long life, and excellent heat dissipation, all while ensuring safety and reliability. This case highlights BG Motor’s commitment to providing customized、high-performance motor solutions that meet the specific needs of the transportation industry.
