He holds a total of 10 patents, showcasing his innovative spirit and technical expertise. His work has significantly impacted the design and functionality of modern machinery.
Latest Patents
One of Lindem's latest patents is the "Symmetrical Multi-Axis Linear Motor Machine Tool." This innovative machine tool features a frame that supports a vertical gantry, which is driven at both the top and bottom sides. The opposed, normal magnetic forces between stator coils and magnets are designed to be substantially equal and self-cancelling. This unique design reduces normal magnetic forces that can increase friction, providing symmetry along the X-axis. A spindle-carrying saddle travels in a vertical slot at the center of the gantry, with left and right linear motors mounted on opposite sides. These identical linear motors ensure that the opposed right and left-hand normal magnetic forces are self-cancelling, thus providing symmetry along the vertical Y-axis. The spindle and ram mounted on the saddle are driven by at least one linear motor to travel along the Z-axis. The symmetry and cancellation of normal magnetic attractive forces reduce the weight and the amount of force needed to accelerate the gantry in the X-direction and the saddle in the Y-direction. The preferred frame is a stationary, box-type structure that encompasses the gantry and spindle, providing an enclosed space that protects the linear motors.
