Provided is an electric moving machine including: a plurality of wheels provided to a vehicle body; traveling motors each provided for the corresponding wheel and configured to drive the corresponding wheel; and a driving-unit control device configured to control driving of each of the traveling motors, in which the driving-unit control device, in a case in which an error is detected in one or some of the traveling motors during traveling, stops the traveling motors with an error detected, determines a combination of traveling motors to improve a balance of driving force in a traveling direction which broke due to the stopping of the traveling motors, and controls, based on the combination, driving of each of the traveling motors with no error detected.

Electric moving machine

A work machine comprises, a drive source, a working unit that includes a rotary member rotated by the drive source and performs a predetermined work by rotation of the rotary member, and a control unit that controls the drive source so that output of the rotary member partially takes different values in one rotation of the rotary member.

Work machine with a rotary member and torque control therefor

A working machine is provided which can suppress the adhesion of rain water, snow, and melting snow to an electrical connecting portion between a battery containing portion side and a battery side. An electrically driven snowplow as a working machine includes a battery pack incorporating a battery, a battery containing portion disposed so as to allow the battery pack to be inserted and removed in a direction inclined from a vertical direction, and an electrode portion configured to be connected with an output terminal of a battery disposed on an upper surface of the battery containing portion.

Working machine

In a cogeneration apparatus having a power generation unit connected to an AC power feed line between a commercial power source and electric load, and an internal combustion engine, a switch is installed between the power generation unit and an outage power output, and the switch is opened to combine the power generation unit with the commercial power source to supply combined power to the electric load if a calculated total engine operation time period is not more than a predetermined time period when the outage is determined not to occur, while the switch is closed to connect the power generation unit to the outage power output, if the power generation unit is determined to be capable of generation power based on an estimated degree of deterioration of the unit when the outage is determined to occur.

Cogeneration apparatus

In an apparatus for estimating a temperature of a heating element such as IGBT mounted on an electronic printed circuit board, a first temperature and a second temperature at positions away from the heating element are detected, and it is determined whether a cooling device is operative. The temperature of the heating element is estimated based on the first and second temperatures using a first equation when the cooling device is inoperative, whereas it is estimated using a second equation when the cooling device is operative, thereby enabling to accurately estimate the temperature of the heating element equipped with the cooling device.

Heating element temperature estimation apparatus

A system-interconnected inverter connected to a commercial system for supplying AC power, which inverter includes a switching device for turning on and off DC power based on a predetermined duty value to output a voltage whose frequency is the same as that of a system power source and a controller for controlling the switching device. The controller changes the duty value of the switching device in accordance with the value obtained by dividing the maximum value by the effective value of the output current from the switching device measured with the system-interconnected inverter disconnected from the system power source.
