Abstract
A power tool comprising a housing and a brushless direct-current (BLDC) motor disposed within the housing. The motor includes a stator and a rotor rotatable relative to the stator. The power tool is configured to generate a power output from the motor that is greater than 1200 continuous hot Watts out such that a quotient obtained by the power output measured in Watts (Wout), divided by an input measured in Volt-Amperes (Vain), and further divided by a volume of the power tool measured in cubic centimeters (cc), is greater than 600 Wout/Vain/cc.
Claims16
A power tool, comprising:
- a housing;
- and
- a brushless direct-current (BLDC) motor disposed within the housing, the motor including a stator having a plurality of windings and a rotor rotatable relative to the stator, wherein the power tool is configured to generate a power output from the motor that is greater than 1200 continuous hot Watts out such that a quotient obtained by the power output measured in Watts (Wout), divided by an input measured in Volt-Amperes (Vain), and further divided by a volume of the power tool measured in cubic centimeters (cc), is greater than 600 Wout/Vain/cc.
