optic sensor pulse motor

[jasonspinmaster]

i have placed a 4.7k resistor instead of the 10k, and it is spinning a little faster.
my optic sensor is a OPB876 (N package)

 i do not understand you when you  said that i should try and bypass the diode from the emitter. how do i do this. if i just connect up i wire the transistor over heats, very fast

[jasonspinmaster]

i have been able to drop the resistance down to a 2.2k resistor not the 4.7k
the battery is at 10.25 volts
placing red pin of meter on base i am getting 0.99volts
from emitter 0.52
collector 12.25 volts

Do you have a full diagram of the circuit, I need to know where the diode from the emitter goes?

the diode goes from emitter to negative in the battery
