Handheld power tool with a brushless electric motor

A power tool, comprising:

• a housing including a power interface couplable to a power source;
• 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;
• a circuit board residing in the housing;
• a switching arrangement mounted on the circuit board and having a plurality of motor switches configured as an inverter circuit, the inverter circuit being configured to receive electric power from the power source via a bus line and switchably output the electric power to the BLDC motor;
• a controller configured to control a switching operation of the inverter circuit to regulate the electric power supplied to the BLDC motor;
• and
• a capacitor mounted on the circuit board and electrically connected across the bus line, 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 a power input of the electric power supplied from the power source measured in Volt-Amperes (Vain), and further divided by a diameter of the motor measured in meters (m), is greater than 10 Wout/Vain/m.
