Honeywell has a higher torque motor, the Herculine series, in a different class. It would seem that if the motor only runs when honewell input voltage is applied through the control circuit, the motor could run 0.

The result of his research is that all except 4 models and all on-off motors have 55 “repositions”, or steps of resolution. Add this item to my cart. I tend to go for Kromschroder GT motors, GT31 usually noneywell GT50 for bigger honewell, they do a good range of different supply voltages and travel times and the end of stroke and signalling limit switches are easy to adjust.

Let’s assume the actuator is a recent model Modutrol IV, model M The pdf scanned, not text, believe it or not is here: I’ll try my Honeywell contact on Monday to see if he uoneywell shed any light on your problem, or if he knows who can.

If you are uncertain or have questions, please email at support controlscentral. We have one of their higher accuracy ones now that will be installed next week. Integral junction box provides NEMA 3 weather protection. I do not know the model off hand, ill get it tomorrow in the shop.

This class of actuator can be had with Modbus, as can Rotork. I suspect the nmber of repositions steps doesn’t matter a heck of lot when the motor drives a damper in an air handler. There are 4 ‘enhanced’ Modutrol IV models, all of which are mA proportional motors, each of which has more than 55 repositions. It is a C We’ll keep you connected! While calling about this issue, I heard, more than twice, two numbers from Honeywell people, 35 or 55 positions for the Modutrol line. JavaScript seems to be disabled in your browser.


The ideal cotnrol position was in between motor reposition-steps.

Ill let everyone know how much more accurate it is. While investigating a “poor control” complaint, I discovered that Barber Colman motors this was 20 years ago used the same die cast housing, same electric motor, same slidewire, but just changed the gear train. Product Data Sheet Coming Soon. It took 3 calls to find someone willing to research this. Motor and circuitry operate from 24 Vac.

Adapter bracket for matching shaft height of older motors is available. Fixed torque throughout the entire voltage range. There’s a different class of electric actuators for the massive valves used in waste treatment plants, by vendors like Rotork, and I’ll bet they’re more than willing to define what hooneywell of resolution their actuators provide.

I did it, it worked. Motors are designed for either normally open or normally closed valves and dampers. But I’ve seen first hand the effect of an acuator that can not resolve sufficient positions to control a gas valve. If the valve is sticking there could be some undesired results. Email to a Friend. It specs the reposition resolution.

Isnt user generated content great! Why not an actuator where you could send the requred position and get feedback on the actual position, maybe even alter the speed of travel, all via serial comms?


The original link I gave was a scanned pdf, whose document number has no other hits on the web.

Usually Ships in 1 – 3 Weeks. The Honeywell text, as usual, is not clear, but the fact that the adjustment setting affects movements in the “opposite direction from the most recent change” seems to be what is happening with regard to your applied changes. The oven lined out nicely with a slower motor and the motor did not hunt. Is this item right for you?

You can also find answers to some common questions on our FAQ page. I am surpised that an “industrial” control motor has such poor performace. Here’s the manual statement: I have a new M in my office and will see how it reacts with different VR3 settings. I have seen that with pneumatic actuators.

Usually Ships in 1 – 3 Weeks Availability: Backing off the tuning constants to slug the controller response down made no difference, the PV was clearly, to the eye, tracking the motor position and the desired motor position could not be achieved.

Single Phase Honeywell Modutrol Motor, Model: M, Rs /number | ID:

Integral honeywelll switches are available factory mounted, or can be field added. Heres another question then, what acctuators does everyone else use for things such as port valve motors? You might also look what happens if the valve is disconnected hondywell the modutrol. The motors accept a current or voltage signal from an electronic controller to position a damper or valve at any point between open and closed.

Ill check to see if it has a dead band.

It sure wasnt easy getting it out of honeywell, I am glad you did. So it follows that your motor doesn’t have the adjustment.
