Developing Power-Packed, Environmentally Conscious Cordless Lawn Mowers

Design for Efficiency, Performance, and Usability

The gas-powered mower had a nice, long run. However, advances in technology and a more eco-conscious consumer landscape ensure cordless electric mowers are well-positioned to overtake their fuel-powered counterparts. Here’s why:

• Cutting grass with a diesel-powered lawn mower for one hour generates the same level of emissions as driving a car for 100 miles.
• By 2034, ride-on electric mowers are projected to hold the majority share of global market revenue, surpassing traditional lawn equipment and signaling a seismic shift in consumer preferences for sustainable solutions.
• In addition to eco-friendliness, electric mowers offer substantial benefits compared to gas-powered models:
  • Easier handling
  • Minimal maintenance (no oil changes or gas refills)
  • Quiet operation
  • Cheaper lifetime costs

Like how drones transformed aerial technology, cordless mowers are set to do the same in lawn care. But only if they deliver enough power and battery life to make consumers’ lives easier.

Balancing Power, User Comfort, and Convenience

For cordless motors to function reliably for the long haul, several systems and components must work together seamlessly — from the battery and charger to the brushless DC motor and controller. 

When designing cordless mowers, engineers should consider a host of factors to ensure peak performance and user-friendliness: 

• Battery Performance: Lithium-ion batteries, typically 18V-36V, with high energy density and fast charging capabilities, are crucial for extended runtime. But maximizing their potential requires proper isolation and an intelligent battery management system (BMS).

• Motor Efficiency: Energy-efficient brushless (BL) DC motors help maximize battery life and power output for cutting different grass types and yield longer run times.

• Integrated Circuit (IC): As the regulator of the BLDC motor, the IC should deliver precise control signals while managing the high currents that power the motor.

• Overvoltage & ESD Protection: Ensuring the motor, battery, and battery charger do not overheat or get damaged by surges or transients is crucial to the safety and longevity of the mower.

It's important to note that there are additional design considerations to consider, such as high-quality blades, safety mechanisms, and noise reduction, all of which contribute to an enhanced user experience.
