With the in-depth development of vibration industry, the use of vibration motor field is also expanding, but for the users who just stepped into this market, want to choose a partner with advanced technology, reliable quality, honest and trustworthy in many vibration motor brands or have cooperated with manufacturers before, Because its quality does not dare to flatter the user that has to change replenish stock channel however also is not an easy thing. Especially for the first time to buy vibration motor users, for many aspects of vibration motor is not very understanding, today xinxiang Tongda vibration motor Co., LTD. This article will mainly focus on the blind spot in the purchase of vibration motor, so that users more clearly buy vibration motor need to pay attention to what matters.

1, vibration motor style

Vibration motor is mainly divided into horizontal and vertical installation styles. Horizontal vibration motor is fastened through the motor anchor bolt hole and vibration equipment installation hole connection, mainly used in large mine screen, vibrating screen, linear vibrating screen, dewatering screen, warehouse wall vibrator, etc., is the main force of vibration motor. Vertical vibration motor is fastening through the motor flange bolt hole and vibration equipment installation hole connection, mainly used in the garden rotary vibration screen, finishing machine, mixing machine and other equipment.

2, vibration motor composition

The structure of vibration motor is more complex, the basic unit is the shell, end gland, fixed rotor, enamelled wire, bearing, lubricating grease, eccentric swing block, cable, terminal post, outlet sleeve, protective cover, sealing ring, standard parts, paint. The process unit is insulation class, protection class.

1. Shell and end gland: it is a metal casting part. The material is gray iron, ductile iron, cast aluminum, cast steel, etc., and it is divided into resin sand and lost mold casting. The shell of our company is cast by environment-friendly lost mold ductile iron. In the past, the eccentric block was used for casting, but now it is basically processed by plasma cutting steel plate.

2, the stator, rotor stator core, stator winding and stand by the high silicon steel sheet guide multilayer superposition of stamping forming, main effect is to produce a rotating magnetic field, high quality silicon steel sheet is high permeability and low iron loss, recycling of low silicon steel sheet is magnetic iron loss, high power loss and electric heating, temperature rise too high, long lines caused by burn.

The rotor consists of rotor core, rotor winding and rotating shaft. The main role of cast aluminum rotor is to output the current generated by magnetic line cutting in the rotating magnetic field. The weight of rotor core is not enough, the excitation current increases, the power factor is reduced, the purity of aluminum is not good or the amount of recycled aluminum is much, which will cause the reduction of electricity rate, the increase of rotor resistance, causing the wire package to heat up and burning the motor. Our rotors are made of large state-owned high conductivity silicon steel sheet and carbon steel.

3, enameled wire: the quality of enameled wire mainly depends on the purity of its copper wire, the higher the purity, the less impurities, the line diameter is consistent, the insulation layer is full without damage, soft, bright color.

The insulation grades of enameled wire are in order: Y/A/E/B/F/H/C. F is relatively high and can work at 155 degrees Celsius. B Lower, 120 degrees Celsius. XV, XVM-A series vibration motors produced by our company are F grade insulation.

4, bearing: bearing is the guarantee of vibration motor quality, the price difference of the same type of bearing is several times or even dozens of times, the quality is obvious. High quality bearing capacity, stable operation, low current, low noise, long service life. Our company adopts domestic and imported genuine bearings.

5, bearing lubrication grease: because the vibration motor allows normal temperature rise of 60 degrees, plus the environmental temperature, the general use of temperature between 70-90 degrees, so the lubrication grease must be resistant to high temperature, otherwise the running loss can not play a lubrication role. Our series of vibration motors are made of imported lubricating grease.

6. Sealing ring: Due to the vibration motor in different environments, using key, play A role of dust-proof waterproof sealing ring is quite common vibration motor without seal design or seal is not going to work, decoration, our company produces the XV, XVM - A series of vibration motor USES waterproof dustproof independent national patent technology, greatly improve the service life of the vibrating motor, IP55 protection level.
