I recently got my Coote 2x72 with 10" wheel and hooked up a HF 1 HP motor which is running on 110.The motor runs the grinder fine,but I've noticed that the motor is getting very hot.After about 15-20 minutes of continuous running,some parts are so hot that it will sizzle if I throw a drop of water on it.It is an agricultural motor made for continuous running,and has not tripped the circuit breaker,nor has the "thermal protector" button on the motor ever popped.Is this normal for a motor??Thanks for any advice in this matter.
