Abstract: In this study, design and rewrite mathematical internal of one motor simulated with nine motor with same internal circuit with different input voltage and load. The internal circuit of motor show the effect of load of the rotation speed torque at starting motor with high moment of inertia. The output of performance of simulation proves the mechanical characteristic. The new mathematical model of BLAC nine motors is design and simulated code generated by using MATLAB. The new mathematical analysis of “Internal circuit of motors” represent by mathematical equations. The specific characteristics of motor depend on mathematical analysis equations. The effect of voltage and loadon speed rotation of motor mechanical and regulation characteristic show high accuracy results where the results of simulation values confirm the motor has highly efficient in terms of possessing high mechanical properties, high range (torque, speed) in this model can use in several techniques such as Direct Torque Control (DTC) and Field Oriented Control (FOC).
