# MAGNETIC INDUCTION IN THE AIR GAP VALVE ENGINE

Compiled expression for the magnetic induction in the air gap of the motor with excitation from permanent mag-nets radially magnetized rectangular cross section, which can be used in the analysis of cross-sectional geometry of the BLDC motor to determine how the optimal values of the bore diameter of the stator, and determine the op-timal value of magnetic induction in the air gap of the motor.
