Engineering Mistakes When Choosing Lawn Mower Motors
Choosing Based Only on Peak Power
Peak power ratings can be misleading.
Continuous torque capability is far more important in mowing applications.
Ignoring Thermal Conditions
Outdoor environments can exceed 40°C ambient temperature.
Always verify:
• Thermal rise data
• Continuous current rating
• Magnet temperature resistance
Underestimating Waterproof Requirements
Many motor failures are caused by moisture ingress rather than electrical defects.
IP65 or higher is strongly recommended for robotic outdoor equipment.
Selecting Low-Efficiency Motors
A 10% efficiency difference can significantly affect battery runtime.
