Why Phone Motor Change to BLDC Motor

Why phone motor change to BLDC motor .

As smart phone develop,phone motor change a lot. First we use coreless cylindrical motor.And then smaller coin vibration motor and SMT motor to linear motor. Now the main phone brand begin to use BLDC motor.

Compare to other motors.BlDC have follow advantage: BLDC motor is contact with traditional motor mechanical BRUSH and commutator surface Compared to BLDC motor drive, the Hall IC is a non-contact driven motor.

Difference with Brush Motor

• Vibration and efficiency, high reliability

• Reduce noise with normal drive

• No contact loss, so long life

• Small electromagnetic wave

Difference with Linear Motor

• High vibration and efficiency, high reliability

• No contact loss, so long life • The IC is placed inside the motor and the overall structure is simple • Unlike Linear, horizontal structure, it is easy to reduce thickness (T)

• Unlike Linear AC, DC is used, so it is 100% interchangeable with existing Brush motors
