Also has the casing that heats as the motor coil of packing into; Described first binding post, second binding post and control switch K and button switch K 1 all are arranged on the casing.
Also have mainly the temperature controller of being made up of temperature sensor and AD converter and single chip machine controlling circuit, temperature sensor is arranged in the casing.
Also be connected with cooling fan FS between live wire that above-mentioned 220V exchanges and the ground wire.
Compared with prior art, this novel beneficial effect is:
1, convenient control bake out temperature, handled easily: this New-type electric machine winding heater processing ease, can artificially control baking motor coil input current according to the capacity of equipment such as motor, coil.Control baking temperature and stoving time.
2, simple, the low cost of manufacture of this new structure.
3, this is novel widely applicable: the utility model motor coil heater can be suitable for synchronous generator, the asynchronous motor of different size, the baking of coil series products equipment.Install or transform Control current simple, that can artificially control the equipment of being heated, make dissimilar firing equipment operations more simple and convenient.Maintenance baking and producer's design that can be widely used in motor, coil series products are produced, and have bigger dissemination.
Description of drawings
Fig. 1 is this novel electrical schematic diagram.
Embodiment
Fig. 1 illustrates, a kind of motor coil heater, control switch K one end connects the live wire of 220V alternating current, the other end connects the anode of controllable silicon SCR through lead, the negative electrode of controllable silicon SCR is connected on first binding post through lead, second binding post is connected through the ground wire of lead with the 220V alternating current, is serially connected with button switch K 1 and resistance R 1 between the silicon controlled control utmost point and the anode; Above-mentioned first, second binding post is used to connect motor coil R.
Also has the casing that heats as the motor coil of packing into; Described first binding post, second binding post and control switch K and button switch K 1 all are arranged on the casing.
Also have mainly the temperature controller of being made up of temperature sensor and AD converter and single chip machine controlling circuit, temperature sensor is arranged in the casing.
Also be connected with cooling fan FS between live wire that 220V exchanges and the ground wire.Fan plays cooling effect in the cooling effect after the oven dry or the process of heating.
Among Fig. 1, control switch K is connected on the live wire.Temperature sensor can adopt thermocouple.Single chip machine controlling circuit is a prior art, as, single-chip microcomputer is delivered to the silicon controlled control utmost point by photoelectric isolating circuit and drive circuit with control signal, thereby realize control to the controllable silicon break-make, perhaps, single-chip microcomputer is delivered to relay by photoelectric isolating circuit and drive circuit with control signal, thereby realizes the control (at this moment, button switch K 1 is substituted by the normally open contact of relay) to the normally opened contact (as control switch K) of relay.
The motor coil heater adopts controllable silicon to trigger one of controller; (one of the supporting fin of controllable silicon, capacity disposes according to customer requirements); Supporting cooling fan (but dividing the capacity configuration) according to the whole current control division of silicon; One of static housing (determining the casing size) according to the different capabilities of heater.Auxiliary products are Temperature-controlled appliance one cover.
New-type electric machine winding heater principle: controllable silicon triggers one of controller and can oneself make, or electronic speed regulation, light modulation, the temperature adjustment product of purchase finished product, note taking off the controllable silicon of buying product during with the purchase product and trigger original paper, get the sampling voltage of input and output from New-type electric machine winding heater silicon controlled rectifier, notice that input and output can not connect instead, then triggering the triggering pin that control line is connected on electronic speed regulation, light modulation, temperature adjustment product.Will consider the definite rational box sizes in heat radiation back when selecting casing, input and output side adopts the wooden link of insulation, adopts the binding post of desired volume.Temperature sensor device one cover of auxiliary products, temperature is higher than when setting maximum temperature, the switch of automatic disconnection relay (replacing button switch K 1 position), protection is heated the too high damage equipment of equipment Yin Wendu.Can determine the size of output current simultaneously according to a thermometer indicates temperature.
