| 20090096401 | POWER TOOL - The controller determines the presence or absence of operation of the trigger switch according to an ON/OFF state of the main contact of the trigger switch and designating the rotation speed of the motor based on a signal outputted from the speed contact. The controller stops the rotation of the motor, after the trigger switch is activated and the main contact is turned ON and the motor is driven according to a signal outputted from the speed contact, when an OFF state of the main contact is detected, only in the case where a signal value outputted from the speed contact is a predetermined value or less. | 04-16-2009 |
| 20090134829 | Wizard For Configuring A Motor Drive System - An electronic line shaft comprising a motor drive comprising a velocity noise filter coupled to receive a feedback position signal and operable to filter the feedback position signal to generate a feedback velocity signal where the noise filter has at least one controllable filter parameter that affects filter operating characteristics and a processing unit operable to execute a wizard for configuring the motor drive, the wizard being operable to receive mechanical characteristic data associated with the motor drive that is provided as input by a wizard user via a user interface and to determine a noise parameter based on the mechanical characteristic data, wherein the at least one controllable filter parameter is adjusted as a function of the noise parameter. | 05-28-2009 |
| 20100001675 | Electric Power Tool - An electric power tool is provided that includes a motor as a driving source, a first operation switch, a first semiconductor switch, and a second semiconductor switch. The first operation switch is operated by a user to be turned ON/OFF. The first semiconductor switch, provided on a current path from the power source to the motor, includes at least one semiconductor switching device. When the first operation switch is OFF, the first semiconductor switch is turned OFF to interrupt the current path. When the first operation switch is ON, the first semiconductor switch is turned ON to close the current path. The second semiconductor switch is provided on the current path in series with the first semiconductor switch and includes at least one semiconductor switching device. The second semiconductor switch closes/interrupts the current path by being turned ON/OFF in accordance with an input control signal. | 01-07-2010 |
| 20100270962 | Washing machine and method for controlling the same - A washing machine and a method for controlling the same are disclosed. The washing machine detects a back electromotive force of a washing motor, and controls output of an alarm sound by analyzing periodicity of a waveform period of the back electromotive force. The washing machine determines whether a child or pet is in a drum washing machine on the basis of the back electromotive force generated from the washing motor, and informs a user or guardian of the determined result. | 10-28-2010 |
| 20110221372 | Windshield wiper control system - The present invention relates to a low-cost windshield wiper control system which can be readily incorporated into existing vehicle systems, particularly into an operator-accessible windshield wiper control unit assembly ( | 09-15-2011 |
| 20120001578 | INVERTER FOR ELECTRIC VEHICLE - An inverter for an electric vehicle includes a speed instruction generating unit, a frequency voltage converting unit, an integrator and a 2-to-3 phase converter. The speed instruction generating unit outputs a speed instruction for changing the rotational frequency of an electric motor based on the on/off of a signal outputted from the accelerator pedal. The frequency voltage converting unit outputs a voltage instruction based on the frequency of the speed instruction. The integrator outputs a rotational angle by performing integration on the frequency of the speed instruction. The 2-to-3 phase converter receives the voltage instruction and the rotational angle and converts the received voltage instruction and rotational angle into three-phase voltage instructions. | 01-05-2012 |
| 20120187881 | CONTROL DEVICE FOR ELECTRIC VEHICLE - In an electric vehicle, a throttle spring restores a throttle opening on the side of a minimum opening when the accelerator is not operated. A driving section drives a motor according to the throttle opening. The throttle spring pushes an accelerator grip to a creep speed reference opening so as to reduce the throttle opening. A creep speed control section supplies a motor driving instruction to the driving section so that the electric vehicle is advanced at minute vehicle speed. The electric vehicle can also be backed at predetermined minute vehicle speed when the throttle opening is smaller than the creep speed reference opening. | 07-26-2012 |
| 20120274254 | Machine Tool and Control Procedure - A machine tool has a tool retainer for retaining a tool, a motor and a drivetrain which couples the motor with the tool retainer for transmitting a torque. A system pushbutton is coupled with a motor control. When the system pushbutton is activated by a user, the motor control controls the motor in such a way that the motor turns in a first sense of rotation for a duration and then in a sense of rotation opposed to the first sense of rotation. The duration is shorter than 100 ms. | 11-01-2012 |
| 20130099711 | CONTROL CIRCUIT AND METHOD FOR AN ELECTRIC MOTOR, IN PARTICULAR FOR DRIVING A WINDSHIELD WIPER - The invention relates to a control circuit ( | 04-25-2013 |
| 20150069945 | VEHICLE POWER WINDOW APPARATUS - A vehicle power window apparatus includes: a driver seat unit and a first non-driver seat switch which is a manual switch provided on a non-driver seat to open and close a non-driver seat window. The driver seat unit includes a switching circuit operated based on a predetermined operation of the first non-driver seat switch. When an extended operation of the first non-driver seat switch set by operating the first non-driver seat switch for a certain time period or more is detected, the control unit drives the switching circuit. After the extended operation of the first non-driver seat switch is released, the control unit fully opens or closes the non-driver seat window in an automatic operation mode by energizing the non-driver seat motor via the switching circuit and the first non-driver seat switch by the power supply. | 03-12-2015 |
| 20150340972 | Automatic Cleaning Method For A Pump System Comprising A Softstarter Arrangement - A method for controlling circuitry of a softstarter arrangement to operate an electric motor for driving a pump is provided, wherein the softstarter circuitry electrically connects the motor to electric mains. The method includes: (i) controlling the circuitry of the softstarter arrangement to accelerate the motor up to full speed in a forward direction; (ii) controlling the circuitry of the softstarter arrangement to decelerate the motor when the motor has run at full speed in the forward direction for a first period of time; (iii) controlling the circuitry of the softstarter arrangement to accelerate the motor up a specified speed in a reverse direction; (iv) controlling the circuitry of the softstarter arrangement to decelerate the motor when the motor has run at the specified speed in the reverse direction for a second period of time; and (v) repeating the steps (i)-(iv) one or more times. | 11-26-2015 |
