(2) Machines such as rice mills, crushers, kneaders, pulverizers, centrifugal pumps, electric planers, drilling machines, edge banding machines, etc. Due to the high spindle speed, single-phase asynchronous motors with two poles must be selected. Machine electric.
(3) Agricultural machinery such as rakes, threshers, hard granule feed machines, oil presses, seed cleaning machines, and edible mushroom bagging machines have a low spindle speed, and a single-phase asynchronous motor with a pole number of four or four poles is required.
2 Determine the motor power based on the work load of agricultural machinery (1) In the operations of Yangchang, soya-bean milk processing, apricot kernel processing, and edible mushroom bagging, the required power is small, and a single-phase asynchronous motor of 0.8-1.1 kW can be selected.
(2) Engaged in operations such as barnyardgrass, kneading, grain threshing, rice milling, grinding, and oil extraction. The load is large. A dual-capacitor single-phase asynchronous motor of 1.5-2.2 kW can be selected. In order to achieve multi-purpose use of a machine and give full play to the efficiency of agricultural machinery, the agricultural products engaged in the above-mentioned operations are best to use a dual-capacitor single-phase asynchronous motor with 2.2 kilowatts and four poles.
3 According to the agricultural machinery nameplate or manual supporting single-phase motor must choose good reputation, quality products.
4 Select the nominal current rating on the motor motor nameplate according to the rated current of the user's power meter and the carrying current of the circuit wire, which should be lower than the rated current of the user's power meter and the carrying current of the circuit wire. The same power should try to use a single-phase motor with a small rated current. If it does not meet the requirements, it should be replaced by a large watt-hour meter and thick wire, and then a single-phase motor with a large rated current.
5 Inquire from the agricultural machinery manufacturer if the distributor has replaced the single-phase motor agricultural machinery that the factory supports and the single-phase motor that is matched with it. The agricultural machinery manufacturer promises to keep the agricultural machinery that can make the factory produce agricultural machinery. Single-phase motor that achieves calibrated productivity. At the time of purchase, the agricultural product can use the sales phone number provided by the agricultural machinery manufacturer to check whether the manufacturer, product trademark, model number, and power of the single-phase motor sold by the seller are the same as those of the single-phase motor supplied by the agricultural machinery manufacturer. .
1 Select single-phase motor according to the spindle speed of agricultural machinery (1) In general, the single-phase motor with high rotation speed of the agricultural machinery and matched with two poles; the spindle speed of agricultural machinery is low, and the number of matching poles is four. Single-phase motor.
