Welcome to Xinxiang City Hongda vibration motor company, my company mainly produces JZO vibration motor, YZD vibration motor, YZS vibrating motor, Enping motor, YZU vibration motor, TZD vibration motor, VB vibration motor, XVM vibration motor, ZDJ vibration motors and other and custom processing of all domestic vibration motor models. 1, after the customers to buy, 2.2KW shaker motor, you need to check the packaging before unpacking is complete, no damage, signs of moisture; 2, vibration motor should be reliable, securely mounted on a vibrating device; 3, remove the two end shields, adjustable at both ends of the eccentric unscrewing bolts: 4, simultaneously lift both ends of the angle adjustable and fixed eccentric eccentric between, so that the desired alignment of the shaft exciting force tick baseline; 5. Tighten eccentric bolts, install protective cover. 6, need to carefully check the vibration motor during transport without deformation damage, parts are complete, whether or loose fasteners off; Welcome Xinxiang City Hongda vibration motor company, my company mainly produces JZO vibration motor, YZD vibration motor, YZS vibrating motor, 3KW shaker motor, YZU vibration motor, 7.5KW shaker motor, TZD vibration motor, VB vibration motor, XVM vibration motor, ZDJ vibration motor, and custom processing of all domestic vibration motor models. Vibration motor is good or aluminum copper is good, there is no copper clad aluminum phenomenon? First, to say that the resistivity, the resistivity of copper is 0.017, the resistivity of aluminum is 0.028. Since then the smaller resistivity greater power over the wire, the current more stable, so the vibration motor line package to use copper wire. Second, the cross-section ratio of copper and aluminum swaps was 0.79: 1, six square copper equal to ten square aluminum. Thick diameter than copper with aluminum, aluminum same stator grooves will fit. By the amount of current per unit area is different, probably copper per square millimeter by 5-8A current, much less aluminum would probably be a 3-5A
