摘要： A motor drive system includes a rectifier circuit (1), a controller (2), a modulator circuit (3) and a direct current (DC) motor (8). The rectifier circuit (1) is configured to convert an alternating current (AC) voltage to a DC voltage. The controller (2) is configured to output a control signal. The modulator circuit (3) includes a pulse generation module (4), a feedback determination module (5), a pulse modulation module (6) and a driving module (7), and is configured to generate a modulated DC driving signal based on the DC voltage and the control signal generated by the rectifier circuit (1) and the controller (2). The DC motor (8) is configured to operate in accordance with the modulated DC driving signal generated by the modulator circuit (3).

摘要： Disclosed is an N-phase electric machine, N being an integer ≥ 3, the electric machine comprising: a housing; i x N stator windings arranged in a fixed manner in the housing, i being an integer ≥ 2; and a rotatable rotor surrounded by the i x N stator windings in the housing; the stator windings are consecutively divided into i subgroups in a circumferential direction, each subgroup having N stator windings, and the electric machine further comprises i current control modules and i temperature measurement devices, each current control module being correspondingly electrically connected to the N stator windings in one corresponding subgroup, so that when the stator windings in the i subgroups are supplied with power by means of the i current control modules, a rotating magnetic field is generated around the rotor, and each temperature measurement device is used for measuring the temperature of one corresponding subgroup in the i subgroups during operation of the electric machine; based on a temperature measurement value of the corresponding subgroup, each current control module independently controls a power supply amplitude of the stator windings in said subgroup during operation of the electric machine.

摘要： A device 1 for detecting rotation direction has a current detector 11 that detects the direction of current flowing in a motor 3, a voltage detector 12 that detects each voltage before and after the motor 3 in a power supply line 4, and a rotation direction detector 13 that detects the rotation direction of the motor 3 on the basis of the direction of the current and each voltage before and after the motor 3. The current detector 11 is connected to points A, B before and after a shunt resistor 5, and detects the direction of the current flowing in the power supply line 4 to form current direction information CI. The voltage detector 12 is connected to points A, C before and after the motor 3, and detects the voltage at each position to form motor terminal voltage information VI. The rotation direction detector 13 detects the rotation direction of the motor 3 using a logical combination of the current direction information CI and the motor terminal voltage information VI.

摘要： The noise removal circuit 1 includes: a differential amplifier circuit 11 that amplifies a voltage change signal indicating a change in motor drive current and outputs the amplified signal; a V/I converting section 12 that converts a control signal formed based on the voltage change signal into a current signal; and a current mirror circuit 13 that changes the tail current of the differential amplifier circuit 11 according to the current signal received from the V/I converting section 12 to thereby control the amplification factor of the differential amplifier circuit 11. The noise removal circuit 1 controls the tail current so that the amplification factor of the differential amplifier circuit 11 decreases as the voltage of the voltage change signal increases. When spike noise is contained in the voltage change signal, the amount of amplification at spike noise portions is suppressed by reducing the tail current and limiting the amplification factor, and a signal from which the spike noise has been removed is output.
