The invention discloses a motor controller which is developed by taking a programmable logical chip (FPGA) as a core and is based on a VME bus. The motor controller and a single-board computer meeting a VME standard can form a motor control system. A hardware structure of the controller mainly comprises a VME backboard socket connector 1, a voltage conversion chip converting +5V into +3.3V, a power supply chip 2 converting +5V into +2.5V, a power supply chip 3 converting +3.3V into +1.2V, a power supply chip 4, a VME bus address signal drive circuit 5, a VME bus data transmission control signal drive circuit 6, a VME bus data signal drive circuit 7, an FPGA chip 8, an optical fiber signal driver 9, an optical fiber transmitter 10 and an optical fiber receiver 11; the mechanical specification of the controller is a standard 6U circuit board 12. By combining a VME bus single-board computer, the invention can realize quick data communication capability and reach a favorable motor control effect. Moreover, becaus
