Description
Technical field
The utility model relates to the motor drive that possesses cooling mechanism.
Background technology
In the past, be provided for the cooling mechanism of the heat that distributes this electric power loop and for consuming the situation of resistance of the regenerated energy returning from this motor having for the power circuit of CD-ROM drive motor with for controlling the motor drive of control circuit of this power circuit, existing.
For example in Japanese kokai publication hei 07-007994 communique, record following servo motor driven control device, it is fixed power source module on fin, then has by thermal insulation barriers regeneration electric discharge resistor.
In motor drive in the past, in the situation of power circuit and regenerated electric power consumptive use resistance both sides heating, will not, there is the hidden danger of device in superheat state in the heat-sinking capability of the radiators such as fin.In this case, although propose to use the high equipment (being large-scale equipment) of heat-sinking capability as the countermeasure of radiator, also brought maximization, the expensiveization problem of device.
Utility model content
Therefore, the purpose of this utility model is to provide a kind of motor drive, and it possesses does not make the radiator structure that just can effectively dispel the heat that maximizes.
In order to reach above-mentioned purpose, the utility model provides a kind of motor drive, and it possesses: for the power circuit part of CD-ROM drive motor; Be used for the control circuit portion of the action of controlling above-mentioned power circuit part; For the cooling mechanism of cooling above-mentioned power circuit part; And for consuming the regenerated electric power consumptive use resistance of the regenerated electric power returning from said motor, said motor drive unit is characterised in that, isolation configuration that above-mentioned regenerated electric power consumptive use resistance and above-mentioned cooling mechanism have predetermined space.
In suitable execution mode, motor drive also has for cooling above-mentioned cooling mechanism and above-mentioned regenerated electric power consumptive use fan motor resistance, shared.
In suitable execution mode, motor drive also has a breather line that surrounds above-mentioned cooling mechanism and above-mentioned regenerated electric power consumptive use resistance.
Brief description of the drawings
Fig. 1 is the figure that represents the summary structure of the motor drive of the first execution mode of the present utility model.
Fig. 2 is the figure that represents the summary structure of the motor drive of the second execution mode of the present utility model.
Fig. 3 is the figure that represents the summary structure of the motor drive of the 3rd execution mode of the present utility model.
Embodiment
Fig. 1 is the figure that represents the summary structure of the motor drive 10 of the first execution mode of the present utility model.Motor drive 10 has: for the power circuit part 12 of CD-ROM drive motor (not shown); Be used for the control circuit portion 14 of the action of controlling power circuit part 12; For the cooling mechanism 16 of cooling power circuit part 12; And for consuming the regenerated electric power consumptive use resistance (being designated hereinafter simply as resistance) 18 of the regenerated energy (regenerated electric power) returning from motor.
Power circuit part 12 is electrically connected with control circuit portion 14, is mutually adjacent to configuration in illustrated example.In addition, cooling mechanism 16 be for example have heat radiation fin keel fin, by with power circuit part 12 butts configure, the heat that power circuit part 12 can be produced is to external cooling.
Resistance 18 has predetermined compartment of terrain isolation configuration with cooling mechanism 16, in illustrated example, connects by least one liner 20.By by cooling mechanism 16 and resistance 18 isolation configuration, between arranges space, makes can not be affected each other from the heat radiation of power circuit part 12 and the heat radiation that carrys out self-resistance 18, thereby both is carried out effectively cooling.
Fig. 2 be the motor drive 10 that represents the second execution mode of the present utility model ' the figure of summary structure.The difference of the second execution mode and the first execution mode is to have for cooling mechanism 16 and resistance 18 are carried out to air cooled shared fan motor 22.Other structure is identical with the first execution mode.Fan 22 is forming, configure to cooling mechanism 16 and resistance 18 both sides' blow air or from the mode that both sides draw air.Can more effectively carry out the heat radiation from cooling mechanism 16 and resistance 18 by fan 22.
Fig. 3 is the figure that represents the summary structure of motor drive 10 〞 of the 3rd execution mode of the present utility model.The difference of the 3rd execution mode and the second execution mode is to have a breather line 24 that surrounds cooling mechanism 16 and resistance 18, and other structure is the same with the second execution mode.As shown in Figure 3, breather line 24 surrounds cooling mechanism 16 and resistance 18, and with the air-supply of fan 22 can by the mode in breather line 24 at two ends (above-below direction both ends in illustrated example) opening.By breather line 24, can be to the air-flow being produced by fan 22 direction around cooling mechanism 16 and resistance 18 or air quantity carry out suitable limiting, thereby can more effectively carry out the heat radiation from cooling mechanism 16 and resistance 18.
In addition, breather line 24 in the situation that not having fan 22, motor drive also can be set, in this case, in order effectively to carry out the heat radiation from cooling mechanism 16 or resistance 18, preferably produce by the air-flow in breather line 24 by some method.
Although in order to limit that heat between cooling mechanism 16 and resistance 18 moves and preferably thermal insulation barriers, as the material of liner 20, is not limited thereto.Particularly second and the 3rd execution mode the same use fan 22 in the situation that, by forming by the high material of the pyroconductivities such as metal the heat radiation that liner 22 can comprise the region of cooling mechanism 16, resistance 18 and liner 20 effectively.
According to the utility model, by by the configuration of cooling mechanism and regenerated electric power consumptive use resistive isolation, make from the heat radiation of power circuit part and to carry out the heat radiation of self-resistance mutually not influenced, thereby can effectively carry out the heat radiation from both.
