摘要： The present invention relates to a motor controller employing bootstrap- capacitor supplies and in particular to the situation where the bootstrap supplies have to be charged, while the motor controller is connected to a spinning and energized motor. The present invention introduces a method of recharging based on choosing a recharging sequence from a set of recharging sequences, where the choice depends on the state of the connected motor and in particular on the back-EMF voltages of the motor.

摘要： The invention relates to a method for measuring currents in a motor controller. Some current sensing devices placed on the motor wires or inside the motor controller provide low amplitude output signals thus complicating sampling and data processing. In order to improve the signal/noise ratio, an oversampling technique is disclosed which makes used of a differential transmission of the output signal. Further, by applying intelligent sorting techniques on the sampled data, a substantial improvement in the signal/noise ratio can be obtained. The invention also concerns a motor controller using this method, and discloses the use of a power card and a control card, where the current sensing device is placed on the power card and a differential amplifier is placed on the control card. The gain of the differential amplifier is controlled by components placed on the power card as well as on the control card.

摘要： A frequency converter for driving a motor, includes a circuit board, having at least one first heat-generating element mounted thereon; a heat sink, connected to the at least one first heat-generating element; a fan, facing the heat sink; and a bracket, for positioning the at least one heat-generating element relative to the heat sink and the circuit board. The frequency converter includes a separating member for separating at least one portion of at least one second heat-generating element from the circuit board to prevent the cooling air guided to the at least one second heat-generating element from flowing to the circuit board. The frequency converter includes an airflow guiding member for guiding the cooling air from the fan to the heat sink and the at least one second heat-generating element and a flow guiding gate dispensing more airflow to the region corresponding to the at least one first heat-generating element.
