Question by: Gene M on Jul 24, 2025, 7:30 PM
Got a transit mixer that's been chewing through motors, wondering if this M39 can hold up to that kind of constant heavy use. What's the torque output on it?
Answer by: Customer Support on Jul 25, 2025, 7:39 PM
For that kind of application, 397 newton metres of torque is what you're working with on this unit. Transit mixers are actually one of the listed applications for this motor, so it's built with that duty in mind. The cast iron construction helps it hold up under the sort of sustained load a mixer puts on a drivetrain. It's not a light-duty part by any stretch.

Would this motor be alright for a transit mixer, given it’s made of cast iron? We run 'em pretty hard out here.

Cast iron construction makes this Danfoss / Eaton M39 motor a solid choice for demanding applications like transit mixers, where durability is key.
