Problems solved by technology

The externally mounted belt 28 therefore prevents efficient use of the planer 2 in certain space-constrained conditions (for example, at the edge of the floor next to the wall).
In addition, these planers are bulky and this problem is exacerbated when trying to power the planer with batteries, as any battery pack would need to be located at the rear of the housing 4 since the housing 4 must accommodate the planing barrel 22 and motor 12 resulting in insufficient space in housing 4

Embodiment Construction

[0052] exist figure 2A battery powered hand planer 102 embodying the present invention is shown in FIG. 3 . The planer 102 has a housing 104 defining a rear handle 106 with a trigger switch 108 for supplying power from a rechargeable battery 110 to an electric motor 112 and including a workpiece engaging surface 137 that is in use when the planer is in use. Lean against the workpiece while in the middle.

[0053] As shown in more detail in FIG. 3 , the motor 112 is a brushless motor having a central stator 114 carrying a field winding 116 connected to the battery 110 via a power module (not shown) that controls the timing of energization of the field winding 116 . The wire 118 is energized. Stator 114 is secured to bracket 120 on housing 104 by end caps 122 , 124 and screws 126 such that stator 114 is non-rotatably mounted relative to housing 104 . One 124 of the end caps has an elongated hole 128 for allowing connection of wires 118 to the power module.

Abstract

A planer (102) having a housing (104) having a shoe (138) and an aperture (136) in the shoe is disclosed. The planer includes a motor (112) mounted adjacent to the aperture in the shoe and comprising a stator non-rotatably mounted to the housing and a rotor arranged substantially coaxially around the stator and adapted to rotate relative to said stator. The planer includes a battery wich is located above the shoe. A pair of blades (132) are mounted for rotation with the rotor and protrude through the aperture to engage and to remove surface material from a workpiece.

Description

technical field [0001] The present invention relates to a battery powered hand planer. Background technique [0002] exist figure 1 One known type of hand-held planer for removing the surface of a workpiece, such as a wooden door, is shown in . Planer 2 has a housing 4 comprising a rear handle 6 provided with a trigger switch 8 for supplying electrical power to an electric motor 12 via a supply cable 10 and a front handle 14 . A shoe 16 having a partially cylindrical recess 19 is mounted to and flush with the bottom 20 of the housing 4 . A planer cylinder 22 having a pair of diametrically opposed blades 24 is rotatably mounted in the recess 19 such that the surface of the planer cylinder 22 protrudes slightly from the recess 19 through the opening 18 in the underside of the base 16 so that the planer 22 Engages the workpiece while on the workpiece (not shown). The electric motor 12 has an output shaft 26 connected to the planing barrel 22 via a drive belt 28 to drive the...
