High power density brushed and BLDC motors for cordless and corded power tools — from 18V drills to 36V angle grinders.
Power tool motors operate in one of the most demanding duty cycles in consumer products — repeated high-current bursts, exposure to dust and debris, wide temperature swings, and significant vibration. The shift from brushed to brushless (BLDC) has been the dominant trend in professional power tools over the last decade, driven by three advantages: longer tool life (no brush wear), higher efficiency (15–25% longer battery runtime), and higher power density in the same form factor.
For cordless tools, the battery voltage directly sets the motor voltage — 18V (5S Li-ion) and 20V MAX (same battery) are the dominant consumer platforms; 36V and 40V MAX are common in professional-grade tools. Brushed motors remain cost-competitive for entry-level corded tools and low-frequency-use cordless models.
BLDC inner-rotor motors, 18–20V, 200–400W peak. High pole count for smooth torque at low speed for drilling; high peak current for impact mode. Integrated thermal protection standard.
High-RPM brushed or BLDC motors for sustained cutting and grinding. 18–36V for cordless; universal motors for corded. Key spec: sustained power rating (not just peak) and thermal endurance.
Brushed DC motors for variable-speed reciprocating motion. High torque at low-to-mid RPM with orbital action capability. Robust carbon brush design for sawdust environment.
Brushless (BLDC) tools offer 20–30% more runtime per charge, longer motor life (no brush wear), higher peak power from the same battery, and electronic over-current protection. Brushed tools cost less upfront and require simpler controllers. For professional users with high daily use, brushless pays back within 6–12 months of use.
We supply motors by electrical specification (voltage, power, RPM, shaft dimensions) rather than branded battery platforms. For OEM tool manufacturers, we can spec and sample motors matched to your battery voltage and mechanical envelope. We do not supply aftermarket parts for branded tools.
Always specify both. Peak power determines how the tool handles overloads and start-up; continuous (sustained) power determines thermal performance in extended use. A motor rated 400W peak but only 150W sustained will overheat quickly in demanding applications. Our datasheets include both ratings and thermal derating curves.
