App note from Precision Microdrives on how to properly connect wires on to vibration motors for reliability. Link here

Vibration motors require electrical power, which must be delivered by wires or PCB tracks to the motor. Precision Microdrives vibrating motors are available in a range of connector forms. From stock, they are available with factory installed leads, terminals, PCB solder pins, or as PCB SMT / SMD options. Solder pins and SMT motors have the advantage of being mounted directly onto the PCB which simplifies the connection process.

App note: Electrical techniques for using different power sources on vibration motors

Application bulletin from Precisionmircodrives on powering vibration motors from different and some cases fluctuating power sources. Link here (PDF)

As vibration motors have a wide variety of applications, they are often integrated into systems which have different power sources. A common concern, in terms of power supply, is adjusting the source power supply voltage to a suitable level for the vibration motor or drive circuitry. This protects the motor, and can ensure a constant level of performance for uses like haptic feedback.
