| 318017000 | PORTABLE-MOUNTED MOTOR AND/OR PORTABLE-MOUNTED ELECTRICAL SYSTEMS THEREFOR | 7 |
| 20110057584 | VARIABLE SPEED SWITCH - A switch for controlling a rotational speed of a motor includes an operation member, a first circuit, and a second circuit. The first circuit includes a brush coupled to the operation member having a contact and also includes a variable resistive plate having a resistance that changes in response to a contact position of the contact point of the brush, so that the first circuit outputs a control signal to the motor according to the contact position of the contact point. The second circuit connects the brush and the resistive plate without through the contact point when the brush is positioned at a given position relative to the resistive plate. | 03-10-2011 |
| 20110215742 | Remote Controlled Circuit Breaker for Battery Powered Riding Toys - A remote controlled circuit breaker for battery powered riding toys and method of using is disclosed. The circuit breaker is capable of being installed into standard electrical systems of battery powered riding toys via complementary connectors. If the child encounters danger while riding, the handler of the remote control can push the “Stop” button to switch the circuit breaker, thus preventing electric current flow through the toy. Once danger is averted, the handler of the remote control can push the “Go” button, which switches the circuit breaker to allow current flow from the battery to the motor, and thus allowing movement of the vehicle. | 09-08-2011 |
| 20120056564 | Electrical Drive With Switchable Coil Sections - The invention relates to an electrical drive having a motor with a rotor and a stationary stator, which has a coil arrangement, and having a motor controller for controlling the motor, with the motor controller being configured to pass current through the coil arrangement in order to produce an excitation field, with the coil arrangement having a plurality of coil winding sections, and with each coil winding section having a plurality of coil sections, wherein the polarity of at least one coil section of the plurality of coil sections of each coil winding section can be selectively reversed with respect to the other coil sections of the coil winding section. The drive is particularly suitable for use for an electrical tool. | 03-08-2012 |
| 20120086365 | WORK APPARATUS HAVING AN ELECTRIC DRIVE MOTOR - An electric chain saw has an electric drive motor defining a motor-specific characteristic line of the drawn-in current as a function of the rotational speed of the motor. A control unit controls the current flowing through the drive motor below an engaging rotational speed to values below the motor-specific characteristic line. In order to generate an operating point the operator can feel in a working region in a predetermined rotational speed band, a control characteristic line of the electric input power of the electric drive motor as a function of the rotational speed is provided above the engaging rotational speed. The control characteristic line is adapted to reduce the electric input power within the rotational speed band to an approximately even mean power so as to cause the torque of the drive motor to increase within the rotational speed band with falling rotational speed. | 04-12-2012 |
| 20120161675 | ELECTROMAGNETISM-TORQUE FRICTION-BALANCING TRUCKLE FOR MOBILE MEDICAL DEVICES - A truckle for a mobile medical device is provided. The truckle includes at least one electromagnetism torque balancing motor mounted on the truckle and configured to balance out friction generated by the truckle. | 06-28-2012 |
| 20120169256 | ELECTRIC POWER TOOL - An electric power tool includes: a motor; a manipulation input receiving unit which receives a user manipulation input for rotating the motor; a mode changeover unit that has one manipulation portion which manipulated by the user; a rotation drive force transmitting unit that switches a transmission mechanism to one of the transmission mechanisms corresponding to the set position of the manipulation portion and transmits a drive force of the motor to a tool output shaft via the switched transmission mechanism; an electric signal output unit that outputs an electric signal corresponding to the set position of the manipulation portion; and a motor control unit that sets the control method of the motor to a control method preset for the electric signal, among a plurality of different types of control methods, based on the electric signal, and controls the motor by the set control method, based on manipulation by the user. | 07-05-2012 |
| 20130293159 | ELECTRICAL SWITCH - An electrical switch, particularly for an electrical appliance having an electric motor. The switch has two electrical supply connections for the supply voltage, particularly for a rechargeable battery, and two electrical motor connections for the supply of voltage to the electric motor. Furthermore, the switch has a control electronics unit, such as a microprocessor, a microcontroller or the like, for executing control processes in the electrical appliance, wherein particularly the control electronics unit operates by means of a piece of software. The switch can also be connected with a data line for communication between the control electronics unit and an external device, wherein particularly one of the electrical motor connections is used as an interface for the data line. Furthermore, the invention relates to an appropriate method for communication by an electrical switch with an external device. | 11-07-2013 |
