摘要： A saw (1) being portable and/or wheeled, such as a wall saw, floor saw or masonry saw, comprising a rotatable circular saw blade (3), a drive motor (5) with an motor output shaft (9) for rotating the saw blade (3), and a transmission (20) for interconnecting the motor output shaft (9) to the rotatable saw blade (3) in order to change an unsuitable high speed and low torque combination of the motor output shaft (9) into a more useable lower speed and higher torque combination at the rotatable tool (3), wherein the transmission (20) comprises two adjustable friction saw protective clutches in parallel, which can be set at a desired predetermined value, so as to limit the maximum size of the forces that the teeth and gears of the transmission (20) are exposed to. No over dimensioning is necessary, and the transmission (20) will make out fine in rough environments. The transmission may be of single-speed or two-speed type.

摘要： The present invention relates to a wall or floor chain sawing device (1), comprising a chain bar assembly (37) which in turn comprises a chain bar (2) having a longitudinal extension (17) and guiding a chain (3) at least partly around its perimeter. The chain bar assembly (37) further comprises a chain bar housing (6) that is attached to, and partially covers, the chain bar (2) and the chain (3). The chain sawing device (1) comprises a motor (9), a track interface (7) that is arranged to co-operate with a guiding track (8), and a power transmission arrangement (10) that is adapted to transfer a motion from said motor (9) to the chain (3). The sawing device (1) comprises a first pivotable support rod (12) and a second pivotable support rod (13), where each pivotable support rod (12, 13) has a corresponding first end (12a, 13a) and a second end (12b, 13b). Each first end (12a, 13a) is at least indirectly pivotably attached to the motor (9), and each second end (12b, 13b) is at least indirectly pivotably attached to the chain bar assembly (37).

摘要： The present invention relates to an electric saw (1) being powered by an external power supply (200) through a multicore cable. The multicore cable includes electrical wires (24, 25, 27) for supplying power to the motors (5, 12, 13) of the electric saw (1) and communication wires (26) for data communication between the electric saw (1) and the power supply (200). Two motors (12, 13) of the electric saw are three phase permanent magnet motors (12, 13), with an outer rotor and an inner stator. Each of the two motors (12, 13) has three Hall Effect sensors (H1, H2, H3) located around the outer rotor. In particular the invention relates to a method of controlling the saw (1) comprising the steps: a) monitoring the electrical position and/or electrical positional changes of the second and/or third motor (12, 13); and b) transmitting it to the external power supply (200); and c) delivering a three phase commuted voltage to the second and/or third motor (12, 13). Further the invention relates to a communication protocol for serial communication between the saw (1) and the external power supply (200).
