36 volt motor for high temp application

36 volt motor for high temp application

36 volt motor for high temp application

(OP)
I am looking for a pmdc motor in a small packaged 1.56"  diameter, 5.1" long shaft to shaft.  The operating specs are as follows
175 C, operate, 200 C survive
Kt (torque constant) approx 8.2 in-oz/amp
Ke (back emf constant) approx 6 V/krpm
no load rpm approx 5000-6000 rpm
The motor is also subject to high shock and vibration.

The motor opens and closes a rotary valve that is run by a gear box.  The motor spins 16 turns one direction, stops and turns 16  turns in reverse.  
We are powered on lithium batteries so we can not pull more than 2.5 Amps at start up or we drop our voltage too much.
Any recommendations on vendors for a motor that might meet this application spec?
