Efficient brushless direct current motor driver capable of setting different lead angles

The invention discloses an efficient brushless direct current motor driver capable of setting different lead angles. A module A and a module B are internally provided with a chain destruction protection unit, a lightning protection unit, a power drive unit, an electrostatic protection unit and a control unit, and the power drive unit is connected with a motor; the module A is provided with 30 stitches; the module B is provided with 23 stitches; the 16 ALA end of the stitches of the module A is used for setting a setting mode of an electric motor phase current lead angle; the 14 UL end of the module A is used for setting an upper limit range of the phase current lead angle; the 18 Gout end of the stitches of the module A and the 19 Gin end of the stitches of the module A are used for setting the gain of a feedback current, so that an automatic lead angle is in the optimum state; the stitch 13 is an LA end and is used for setting when the lead angles are fixed. The efficient brushless direct current motor driver has obvious advantages that the size is small, the adjustment is easy, the reliability is high, the anti-jamming capability is strong, the cost is low, the efficiency is high, and the noise is low.
