Introduction
Masumi Nishimura is a notable inventor based in Anjo, Japan. He has made significant contributions to the field of electric working machines, holding 2 patents that showcase his innovative spirit and technical expertise.
Latest Patents
Nishimura's latest patents include an electric working machine that features an inverter and a controller. This controller is designed to switch a current conduction pattern via the inverter and perform PWM control of a conduction current to a brushless motor. The controller incorporates various switching patterns that are adjusted for each commutation timing, allowing for different on and off states for different switching elements. Additionally, the controller can detect the rotational position of the brushless motor by analyzing the inductance variations produced by the switching pattern, thereby setting the appropriate commutation timing.
Another significant patent by Nishimura is focused on an electric working machine that includes a motor, a speed setting unit, a load detection unit, a determination unit, and a parameter setting unit. This invention calculates an estimated value of heat generation in the motor and determines if the motor is in an overload state when this value exceeds a predetermined threshold. The parameter setting unit adjusts the parameters used for these calculations based on the rotation speed set by the speed setting unit.
