Hi every body>>> i am newbie here guys i need your help in H-bridge circuit
i have 35 volt dc motor and also i can drive it with less that 35 volt, i want to drive it FW and BACKWARD by H-bridge cct >>> i connected the cct below

with out diodes and with resistors 33 ohm value >>> the transistor i used is tip41c< i used this type only for the connection , i have a DAQ3001 (data acquisition personal 3001) device that used for experiments and taking measurements from sensors and driving actuators, but my question is when i connect the bases of the transistors i can not drive the motor.
i measured the output of the Daq device its about 3.95 volts dc , so i dont know where is the problem please help me>>

 

Your H-bridge is a little wrong

 

thanks for your answer..
i think i didnt use pnp transistor
and the diodes>>>
is the lower base is always 5 volt (high)?
is the pwm is applied to the upper base?
thnks
