I don't know if any of these options will be appropriate for you, but you could try:
-Reducing the duty cycle of the motor's "ON" or "running" time
-If the motor is in an enclosure, make sure that there air can flow through the enclosure
-Use a fan to force air across or around the motor.
Are the plastic parts being affected by the motor temperature of 150°F? I would think that plastic would have much higher melting point that 150°F.
