Our SCW0625S-01D brushless BLDC coin vibration motor uses helical spring contacts which are designed to mate with corresponding contact pads on the PCB. This motors brushless design makes it ideal for Hi-Rel applications or those with high duty cycles. A driver IC is built imbedded within the motor, so no external driver IC is required. Simply apply DC voltage as you would a normal brushed DC motor. Voltage polarity must be observed or you will damage the internal driver IC. Since reflow solderable SMD coin vibration motors are not yet available, a BLDC coin vibration motor like this, with spring contacts, can be used to streamline the assembly process by eliminating the need for soldering wires.
