Unveiling the Power Behind the Climb: Why Torque Matters in Electric Wagons

When you’re hauling the whole family’s essentials up a steep hill on a scorching summer day, the last thing you want is to be huffing and puffing. Outisan’s electric wagons make uphill climbs a breeze, saving up to 90% of your effort. But how does this technology work? Let’s dive into the science behind our powerful motors and explore why they excel at conquering hills.

The Power Behind the Climb

The key to Outisan’s uphill power assist feature lies in the motor technology. Two key performance indicators of a motor are power and torque. Power is maximized at high speeds and is more related to top speed. Torque, on the other hand, is the measure of a motor’s turning force and directly affects acceleration, load-carrying capacity, and hill-climbing ability. Since electric wagons typically match human walking speeds, power is less critical. Torque is the real performance metric that matters. Based on our previous experiment to explore the powertrain system, approximately 20 Nm of torque is needed to pull a 150 lbs of payloads up a 10-degree incline. 

A Close Look at Motor Types

Different types of motors offer varying levels of performance for uphill assistance. Generally speaking, motors of electric wagons can be categorized into four main types: brushed vs. brushless, and direct-drive vs. geared.

• Brushed vs. Brushless: Brushless motors are more efficient and powerful than brushed motors due to the absence of friction from brushes. Brushed motors, on the other hand, experience wear and tear on the brushes, reducing efficiency and lifespan. Also, brushless motors are quieter and more reliable.
• Direct-drive vs. Geared: Direct-drive motors drive the load directly without a gearbox, offering high efficiency,low noise, and high precision. Geared motors, in contrast, use gears to increase torque but can introduce backlash and reduce precision.

Given the need for precise control and immediate response to user movement in electric wagons, Outisan primarily uses brushless direct-drive motors. These motors are durable, waterproof, and exceptionally quiet, making them ideal for outdoor use. In contrast, many other electric wagons on the market adopt brushed geared motors. While these motors can provide the same level of torque at a lower cost, they suffer from drawbacks like noise, shorter lifespan, poor controllability, and lower precision.

At Outisan, we believe in choosing the best technology path, even if it means investing more. That’s why we prioritize brushless direct-drive motors across our entire consumer and prosumer product lines. While it might be challenging to balance performance, weight, and cost, our engineering expertise and supply chain advantages enable us to deliver superior products, empowering users to interact with nature with less effort. By choosing Outisan, you’re not just getting an electric wagon; you’re investing in a product that’s been meticulously engineered for peak performance.
