A power tool is provided including a power supply interface receiving a removable battery pack, a brushless direct current (BLDC) motor including a rotor and a stator, and a multi-phase inverter bridge circuit. A controller is provided to output drive signals to the inverter bridge circuit to control flow of current from to the motor, where each drive signal is activated within each corresponding phase of the motor within a conduction band. The controller is configured to control a length of the conduction band at a variable value within a first torque range below a torque threshold and at a substantially constant value within a second torque range above the torque threshold. The torque threshold is greater than approximately 1 Newton-meters and the motor produces a maximum power output of at least approximately 1250 watts at the torque of approximately 1 Newton-meters.

High-power battery-operated power tool

A power tool is provided comprising: a motor, an output shaft driven by the motor along a longitudinal axis, a fan rotationally coupled to the motor to generate an airflow, and a housing comprising two calm shells mated together to support the motor and forming a back wall behind the motor along the longitudinal axis. The rear wall includes a plurality of air intakes. An end cap is attached to the housing adjacent the rear wall with an air gap therebetween. The airflow generated by the fan enters through the air gap in a substantially radial direction, then passes through the plurality of air intakes to enter the housing in thermal contact with the motor.

Power tool

A wall panel system including a first wall panel, the first panel including at least a first panel hook portion. The system also including a second wall panel having a different configuration than the first wall panel. The second panel includes at least a second panel hook portion and a third panel hook portion opposing the second panel hook portion. The first wall panel is configured to engage with the second wall panel to create a wall panel assembly.

Wall hanging system

A total task vehicle (TTV) may operate indoors to move a variety of different types of materials and accomplish a variety of different types of tasks, using tools and accessories powered by/connected to the TTV. One or more high power density (HD) battery packs may provide both 240V DC to 380V DC and 120V AC power to propel the TTV and also to function as a generator for tools and accessories attached to the TTV. A high torque/high speed convertible drive system may allow the TTV to operate in a ride-on mode, a walk-behind mode, providing for flexibility and adaptability in use of the TTV.

Total task vehicle

A jobsite computer network has a local server connectable to a remote server via the internet, a network access transceiver connected to the local server, and a wireless device in wireless communication with the network access transceiver. The network access transceiver receives a message from the wireless device and sends a message to the local server. The local server utilizes information from the message to determine the location of the wireless device. The network access transceiver and/or the wireless device generate data which is sent to the remote server.

Construction jobsite computer data network and location system

A motor assembly is provided including a stator and a rotor. The stator includes a stator main body defining a longitudinal axis, stator teeth projecting radially from the stator main body, stator windings wound around the stator teeth, and two winding terminals provided for each stator tooth extending away from the stator main body substantially parallel to the longitudinal axis. A circuit board is oriented along a radial plane adjacent the stator. The circuit board includes a central through-hole through which a rotor shaft extends, at least one magnetic sensor mounted on a surface of the circuit board around the central through-hole configured to magnetically interface with the rotor, peripheral openings arranged to receive the winding terminals of the stator, and conductive routings extending from the peripheral openings to connect the stator windings in a series or a parallel configuration and/or a wye or a delta configuration.

Circuit board for connecting motor windings

An interchangeable electro-mechanical lock core for use with a lock device having a locked state and an unlocked state is disclosed. The interchangeable electromechanical lock core may include a moveable plug having a first position relative to a lock core body which corresponds to the lock device being in the locked state and a second position relative to a lock core body which corresponds to the lock device being in the unlocked state.

Electro-mechanical lock core

A system for remotely retrieving sensed conditions at one or more building components. The building components are remote or numerous so that a wireless collection of the sensed conditions provides a significant benefit to a builder or building operator. A remote transceiver sends a wireless signal to a building component. The building component includes an onboard transceiver. At least some of the energy from the transmitted wireless signal is received by the onboard transceiver, sent to a storage device, and stored therein. The stored energy is used to operate a sensor for sensing an onboard condition. The onboard condition is then wirelessly transmitted by the onboard transceiver back to the remote transceiver to be displayed.

System for wireless retrieval of measured component data

A power tool is provided including a power supply interface receiving a medium-voltage-rated removable battery pack having a maximum rated voltage in the range of 40 to 80 volts, and a brushless direct current (BLDC) motor. The motor includes a rotor and a stator having at least three stator windings corresponding to at least three phases of the motor, the rotor being moveable by the stator when the stator windings are appropriately energized within the corresponding phases. A multi-phase inverter bridge circuit is disposed between the power supply interface and the motor, and a controller is configured to output drive signals to the inverter bridge circuit to control flow of current from the battery pack to the motor such that the motor produces a maximum power output of at least approximately 1750 watts at a torque of approximately 1.5 to 2 Newton-meters.

A battery-powered motor may include an electric motor, a controller, and a housing. The electric motor may be wound to enable the battery-powered motor to achieve a non-limited motor maximum motor revolutions per minute (RPM) for at least one specified battery. The controlling current may include limiting current to the electric motor at lower RPMs, and limiting the current to prevent the RPM of the electric motor from exceeding a limited maximum motor RPM which is lower than the non-limited motor maximum RPM. The housing may enclose the electric motor and the controller and the specified battery. The housing may have a form factor to engage with a machine that engages with an internal combustion engine that has a maximum engine RPM that is approximately the same as the limited maximum motor RPM.

Battery and motor system for replacing internal combustion engine

When providing alternating current (AC) power to operate AC powered devices such as power tools (such as drills, table saws, miter saws), equipment (such as lawn mowers), and consumer products (such as refrigerators, television, lights) without being tied to a fixed utility power supply typically requires a generator (such as an internal combustion engine based generator) or a battery powered inverter. In order to meet power and runtime needs for these devices, a battery powered inverter must be relatively large and expensive. This simple fact prohibits their use in many environments.

Battery pack, power tool and battery pack charger system

A battery pack and charger system includes a first battery pack having a first set of battery cells and configured to provide only a first operating voltage and a second battery pack having a second set of battery cells and configured to provide the first operating voltage and a second operating voltage that is different from the first operating voltage and a battery pack charger configured to be able to charge the first battery pack and the second battery pack.
