Senix technology of brushless motors increases energy efficiency by up to 92% (compared to 75% for traditional brushed motors) through the elimination of carbon brush friction losses, for instance, in its 40V Li-ion chainsaw whose power density is 3.8W/cm³ (2.6W/cm³ for brushed versions) when sawing oak at a density of 800kg/m³. Cutting speed increased by 46% (15cm²/s compared to 10.3cm²/s). According to the test of German TUV Rheinland 2023, brushless motor speed variation is controlled at ±1.2% (±4.5% for brush motor), so the standard deviation of the grass cutting throwing distance of the Senix commercial lawnmower is lowered from ±1.8m to ±0.4m in full load operation, and the uniformity is elevated by 78%.
In terms of durability, brushless technology extends the average tool life of Senix tools to 1,500 hours (800 hours for brushed motor tools), reduces gear wear to 0.02mm/ 1000 hours (0.08mm for brushed models), and reduces service frequency from 6.3/1000 hours to 1.8/1000 hours. As a typical example of Senix 60V brushless electric drill, its bearing load performance is up to 220N (150N of brush motor), continuously drilled 10mm steel plate rise is only 28 ° C (52 ° C of brush motor rise), its heat efficiency increases by 86%, and motor life can extend by 83% through intelligent temperature control algorithm.
The environmental and energy benefits are staggering: the Senix brushless tool records a current loss of 8.2A (12.5A for brushed equivalents) at 50% load, the operating time per charge is extended to 120 minutes (75 minutes for brushed equivalents), and the carbon emissions are reduced to 0.10kg/kWh (0.18kg/kWh for brushed motors). For example, its brushless hair dryer has 6.2m³/(min·kW) for the unit energy efficiency at 75m/s wind speed mode, 51% better compared to model brush 4.1m³/(min·kW), with the noise peak lowered to 89 dB from 102 dB. According to a study in the Journal of Power Tool Engineering in 2023, the vibration level of Senix brushless motor is 1.5m/s² (3.2m/s² for brush models) only, and the muscle fatigue index of the user decreases by 63% after 2 hours of usage.
Technical advantages: Senix brushless motor is still able to provide 95% nominal power at -15 ° C (only 65% for brushed motors), and insulation impedance is still greater than 100MΩ in 90% humidity environment (≤50MΩ for brushed motors). For example, the brushless high pressure washer operates continuously at 40 ° C for 3 hours, with a rate of pressure fluctuation ≤±2% (±7% for brush models), and constant water flow rate at 6L/min (error ±0.15L). Market statistics also show that Senix brushless tools experience a 72% reduced failure rate versus the alternatives, North American professional user sales in 2023 increased from 38% to 57%, and the five-year cost of ownership decreased by 44% (from $820 to $460).
Intelligent control enhances performance enhancements further: The FOC algorithm of the Senix brushless motor reduces the torque response time to 0.05 seconds (0.3 seconds in brushed motors), for example, when the trimmer encounters a 30mm diameter branch, the temporary torque is increased from 28N·m to 40N·m, and the cutting success rate is 99.8% (92% in brushed models). The BLDC (Brushless DC) motor and ECU co-control reduce the battery life error rate from ±8% to ±1.5%, and reduce tool weight by 18% through load adaptive adjustment (e.g., the electric chainsaw from 3.2kg to 2.6kg). The overall performance index (CPI) for Senix brushless equipment was 9.7/10, a 54% improvement over brushed competitors’ average 6.3, redefining the standard for energy efficiency in outdoor power equipment, according to the Global Tool Show 2023.
