1, the motor at its nominal rated voltage, the comprehensive performance of the work is good, it is recommended that the design of the phone circuit when the operating voltage as close to the rated voltage design.
2, to the motor power supply control module should consider its output impedance as little as possible, to prevent the load output voltage drop, affect the vibration.
Locked rotor current for 3, column motor inspection or test, locked rotor time shoulds not be too long (less than 5 seconds is appropriate, because the stall when all the input power are transformed into heat energy P=I2R, time is too long may lead to higher coil temperature rise and deformation, affecting performance.
4, with support of the motor is installed in the design of the positioning slot, with the mobile phone shell gap can not be too large, otherwise may produce additional vibration, mechanical noise, the rubber sleeve fixed can effectively avoid the mechanical noise, but it should be noted that housing positioning groove and the rubber sleeves should adopt an interference fit, otherwise it will affect the motor vibration output vibration sense decline.
To avoid strong magnetic area 5, transfer or use, otherwise may cause the motor magnet magnetic distortion and influence the performance of table.
6, pay attention to the welding temperature and welding time, recommended the use of 320 degrees 1-2 seconds, the time is too long and the temperature is too high may damage the wire insulation.
7, remove the motor from the packing box or in the welding process to avoid pulling the lead wire, also does not allow multiple large angle bending leads, otherwise there may be damage to the wire.
