Abstract:
A motor drive device can improve the accuracy of detection of malfunction in a fan. The motor drive device includes a fan, a fan controller for controlling the fan, a rotation speed detecting part for detecting the rotation speed of the fan, a relationship acquiring part for acquiring a relationship between a time elapsed from a time point, at which the fan controller changes the rotation speed, and the rotation speed detected by the rotation speed detecting part, a malfunction determining part for determining whether the relationship acquired by the relationship acquiring part is different from a predetermined standard, and a malfunction signal generating part for generating a signal representing the occurrence of malfunction in the fan, when it is determined that the relationship is different from the standard.
Abstract:
A motor driving device capable of reliably detecting a malfunction in the performance of a heatsink. The motor driving device includes a heat generating element, a heatsink, an electric power detecting part for detecting a consumed power of the heat generating element, a temperature detecting part for detecting a temperature of the motor driving device, a temperature change calculating part for calculating, as a detected valuation, an amount of change in the temperature within a predetermined time, a reference determination part for determining a reference amount of change in the temperature based on the temperature and the consumed power, and a temperature change judging part for comparing the reference amount of change with the detected amount of change, and judges whether the detected change is different from the reference change.

Abstract:
The motor driving device is to be mounted to a control panel, and includes: a motor driving device main body; a radiator disposed to face a rear surface of the motor driving device main body; a fan motor unit being disposed above the radiator and being withdrawable through an area above the motor driving device main body; and a floor sheet member configured to be laid out along a withdrawal route of the fan motor unit in a process of withdrawing the fan motor unit.
Abstract:
A motor driving device includes a mounting member including a mounting hole; a fan unit configured to be fixed to the mounting member, the fan unit including a lid disposed to cover the mounting hole; a restricting member configured to restrict movement of the lid by sandwiching the lid between the restricting member and the mounting member; and a guide mechanism configured to guide an operation of the restricting member moving relative to the lid from a non-restricting position where movement of the lid is allowed to a restricting position where movement of the lid is restricted.
Abstract:
Disclosed is an injection molding system including: a state observation section observing, when injection molding is performed, physical-amounts relating to the injection molding that is being performed; a physical-amount data storage section storing the physical-amount data; a reward-conditions setting section setting reward conditions for machine learning; a reward calculation section calculating a reward based on the physical-amount data and the reward conditions; an operating-conditions adjustment learning section performing machine learning of adjusting operating conditions based on the reward calculated by the reward calculation section, the operating conditions, and the physical-amount data; a learning-result storage section storing a learning result of the machine learning by the operating-conditions adjustment learning section; and an operating-conditions adjustment-amount output section determining and outputting an operating condition to be adjusted and an adjustment amount based on the machine learning by the operating-conditions adjustment learning section.
Abstract:
A motor drive device capable of attaching a fan unit to a mounting member more easily. The motor drive device includes the mounting member formed with a mounting hole, the fan unit including a lid positioned facing the mounting member to cover the mounting hole and being fixed to the mounting member, and a restricting member movably attached to the lid, the restricting member being movable between a restriction position for engaging with the mounting member and a non-restriction position for releasing from the mounting member.
Abstract:
A motor drive device is fixed to a wall part of a housing and comprises a duct having an inflow port and an outflow port of air. A main body part of the duct functions as a heat-sink unit which releases heat into the duct. The duct is arranged inside the housing. The inflow port and the outflow port are formed so that outside air can flow through openings formed in the wall part.
Abstract:
A heatsink includes: a heatsink main body; a flange portion formed on the heatsink main body; and a filter plate detachably attached to an end portion on an inlet side of the heatsink main body. In the state where the filter plate is attached to the end portion on the inlet side of the heatsink main body, an outer shape of the filter plate is larger than an outer shape of the end portion on the inlet side of the heatsink main body. An insertion hole formed in the flange portion allows insertion of the filter plate to be inserted. A flange is formed on the filter plate and at an end portion on a side opposite to a forefront end of the filter plate in an insertion direction.
Abstract:
A motor drive device detects the malfunction of a flow path in a heat sink based on the temperature of the device. The motor drive device includes: a temperature detection part which detects the temperature of the motor drive device; a temperature change calculating part which calculates the degree of change of the temperature with respect to time when the rotation number of a fan is controlled to a lower rotation number than a regular rotation number; an malfunction determination part which determines whether or not the degree of the change is different from a predetermined standard; and an malfunction signal generation part which generates a signal indicating that malfunction occurs in fluid flow when it is determined that the degree of the change is different from the standard.
