A motor adjustment method adjusts a motor (M) driven by a control device (100). The motor adjustment method includes: acquiring forward rotation information indicating a change in a value of a current flowing through a drive unit (110) at the time of a rotor (310) rotating in a forward direction when a Hall sensor setting position is changed; acquiring reverse rotation information indicating a change in a value of a current flowing through the drive unit (110) at the time of the rotor (310) rotating in a reverse direction when the Hall sensor setting position is changed; and determining a Hall sensor adjustment position on the basis of the forward rotation information and the reverse rotation information. The Hall sensor adjustment position indicates a position obtained by adding a correction amount to the Hall sensor setting position.

To provide a rotor manufacturing apparatus capable of reducing manufacturing cost for a rotor including a magnet fixed with a resin. A rotor manufacturing apparatus (1) includes: a first mold (3) including a resin receive space portion (31) receiving a resin to be supplied into an accommodation hole (212), and a flow path (32) through which the molten resin flows into the accommodation hole (212); and a second mold (4) configured to sandwich a rotor main body (21) in conjunction with the first mold (3). The first mold (3) includes: a first mold main body (34) including the resin receive space portion (31); a runner plate (35) having a flat plate shape and including a flow path main body (321) of the flow path (32), the runner plate (35) being detachable from the first mold main body (34); and a plurality of gate plates (36) each having a flat plate shape and each having a through-hole (361), the gate plates (36) being detachable from the first mold main body (34). A resin outlet (322) of the flow path (32) includes the through-holes (361) in the gate plates (36), the through-holes (361) communicating with one another in the state in which the gate plates (36) are stacked on top of one another in the thickness direction.

One embodiment of the gate drive circuit according to the present invention drives a switching element and comprises: a charging circuit that charges the input capacitance of a switching element by applying a gate voltage to the gate terminal of the switching element; and a discharging circuit that discharges the input capacitance. The charging circuit has: a first charging path having a series circuit in which a first switch and an inductor are connected in series between a first terminal and a first node; and a second charging path in which a second switch is connected between the first terminal and the first node. When the switching element is turned on, charging is performed through the first charging path after charging through the second charging path. The discharging circuit has a configuration in which a path through which the discharge current flows from the gate terminal is switched between a first discharging path and a second discharging path having a resistance value higher than that of the first discharging path.

A motor module (100, 1001) includes a motor (1) and a casing (3, 7). The casing (3, 7) has a partition wall portion (300, 700). The accommodation space (30, 70) has a first accommodation space (310, 710) and a second accommodation space (320, 720). The partition wall portion (300, 700) has a base portion (301, 701) that partitions the first accommodation space (310, 710) and the second accommodation space (320, 720) in an axial direction. The base portion (301, 701) has a wiring portion (4, 8). The wiring portion (4, 8) has a lead-out port (41, 81) and a guide groove (42, 82) extending from the lead-out port (41, 81). The lead wire (Le) is led out from the lead-out port (41, 81) and disposed in the guide groove (42, 82). The casing (3, 7) has a tape member (51) and a sealing member (52). The tape member (51) covers at least a part of the wiring portion from below. The sealing member (52) is disposed in at least a part of a space defined by the wiring portion and the tape member (51).
