PURPOSE:To provide a motor rotation controller for electric automobile in which a clutch can be operated smoothly and slip can be reduced remarkably in a clutch disc and a flywheel. CONSTITUTION:A speed control circuit 1 receives outputs from an r.p.m. detecting means for motor 2, an r.p.m. detecting means 3 for clutch shaft, and a clutch operating state detecting means 4. The speed control circuit 1 is constituted of a microcomputor system comprising an MPU, a ROM, an A/D converting circuit, a D/A converting circuit, and the like, wherein a control program for performing control after operation of clutch before connection of clutch is stored in the ROM of the speed control circuit 1. The speed control circuit 1 controls r.p.m. of motor such that the r.p.m. of the motor detected through the r.p.m. detecting means for motor 2 matches with the r.p.m. detected through the r.p.m. detecting means for clutch shaft 3. |
