For clock and anti clock, use a H Bridge configuration.

i know how to drive 12v dc motor with H -bridge (l293D) with logical values 0 and 1
can you please tell the circuit specification for h-bridge for driving 180v dc motor with logical inputs from micro controller
 

How many levels of speed do you want? Remember more the levels, higher the PWM speed. So decide levels in a conservative manner. Lower PWM speeds will result in easy practice implementation

can you please tell which h-bridge ic like(l293d) is usefull to drive 180v dc motor with clockwise and anti clockwise rotations and as well as with speed control
 

hello tahmid,
i have used the same circuit with ir2101 as mosfet driver ic. but the problem comes that motor dosent rorated continuously. it starts and den get stop den again start den stop. like that it is happening. can you please suggest me what to do for this problem. Please its realy urgent for me. Thank You
