MY6812 150W 12V 2750RPM DC Motor for E-bike Bicycle
The MY6812 is a high-performance 150W brushed DC motor engineered specifically for e-bike and electric bicycle applications, delivering reliable torque at 2750 RPM with a compact 12V operating voltage. Professional e-bike manufacturers, DIY electric vehicle enthusiasts, and retrofit specialists rely on this motor for its consistent power delivery, thermal stability, and proven durability in demanding cycling conditions. This motor solves the critical challenge of converting conventional bicycles into efficient electric-assisted vehicles while maintaining lightweight design and responsive acceleration characteristics.
Product Overview
The MY6812 DC motor operates on the principle of electromagnetic induction, where current flowing through the armature windings generates a magnetic field that interacts with permanent magnets in the stator, producing continuous rotational force. At 150W rated power and 2750 RPM, this motor achieves an optimal balance between torque output and speed for direct-drive or geared e-bike hub applications. The brushed commutation system ensures smooth power delivery across the entire RPM range, making it ideal for variable-speed control through PWM (Pulse Width Modulation) controllers commonly used in e-bike systems. The compact form factor and sealed bearing design minimize friction losses while protecting internal components from moisture and dust ingress typical in outdoor cycling environments.
What distinguishes the MY6812 is its thermal management capability and robust construction specifically tailored for e-bike duty cycles. The motor's winding insulation is rated for continuous operation under moderate load conditions, while its mechanical design accommodates both direct-wheel mounting and sprocket-driven configurations. The 12V nominal voltage aligns perfectly with standard e-bike battery packs (typically 36V systems using three 12V cells in series), enabling straightforward integration into existing e-bike electrical architectures. The motor's efficiency curve peaks between 40-80% load, delivering maximum energy conversion during typical pedal-assist acceleration phases.

How to Use
Installation of the MY6812 motor requires mounting it within the bicycle wheel hub using the provided flange connections and securing fasteners. Ensure the motor shaft is properly aligned with the wheel axle to prevent binding or lateral play that could cause uneven power delivery or mechanical noise. Connect the motor leads to your e-bike controller (typically a 36V PWM controller rated for 12V motor operation) with proper polarity marking, usually red for positive and black for negative terminals. Use appropriately gauged wiring (minimum 10 AWG for 12.5A current) with inline fusing rated at 15-20A to protect the electrical circuit from short-circuit conditions.
For optimal performance, configure your motor controller with appropriate throttle response curves and current limiting parameters to prevent thermal overload during extended high-power demand. Monitor motor temperature during initial testing sessions, as sustained operation above 80°C may reduce bearing lubrication effectiveness and insulation life. If implementing regenerative braking, ensure your controller supports bidirectional operation and includes appropriate freewheeling diodes to prevent back-EMF damage. Regular maintenance involves checking bearing preload annually, inspecting brush wear every 200-300 operating hours, and maintaining clean electrical connections to minimize voltage drop losses across the power circuit.
Frequently Asked Questions
What is the maximum continuous current the MY6812 motor can safely handle?
The MY6812 is rated for 12.5A continuous current at nominal 12V operation, which corresponds to its 150W power rating. Peak current during acceleration can reach 18-20A for brief periods, but sustained operation above 15A will generate excessive heat and reduce motor lifespan. Always use a current-limiting controller with thermal cutoff protection to prevent damage.
Can the MY6812 motor support regenerative braking for energy recovery?
Yes, the brushed DC motor design inherently supports regenerative braking when paired with a bidirectional motor controller. During braking, the motor acts as a generator, converting kinetic energy back into electrical energy that charges the battery. However, regenerative efficiency is typically 60-70% due to brush friction losses, and the system requires a controller with anti-parallel diodes and charge regulation circuits to manage the recovered energy safely.
What is the expected motor lifespan and maintenance schedule?
With proper maintenance, the MY6812 typically delivers 500-1000 operating hours before brush replacement becomes necessary. Sealed ball bearings require no lubrication but should be inspected annually for play or noise. Brush wear accelerates with high current operation and frequent direction reversals, so monitoring commutator condition and brush length every 200 hours of operation is recommended. Complete motor overhaul or replacement is typically more cost-effective than rebuilding at end-of-life.
Can I use the MY6812 with a 24V or 36V power supply instead of 12V?
Operating the MY6812 above its rated 12V nominal voltage will cause excessive current draw, rapid brush wear, and potential motor burnout due to insulation breakdown. The motor is specifically designed for 12V operation with a maximum safe voltage of 14V. For higher voltage e-bike systems, use appropriately rated motors or implement voltage-regulating converters, though this reduces overall system efficiency.
