Bonjour, je sais que cette discussion date un peu, mais je poste ici car je rencontre exactement le même problème avec mon tapis de course. Tout fonctionne correctement, mais il manque de couple : lorsque je monte dessus, il peine et ralentit sous mon poids. J'essaie de réparer la carte depuis des semaines, mais le problème vient peut-être du moteur. L'avez-vous testé avec un autre moteur ? J'ai démonté le mien et les aimants semblent encore puissants.

Hi, I know this is an old thread, but I'm posting here because I'm having the exact same issue with my treadmill. Everything works fine, but it lacks torque—meaning when I get on the treadmill, it struggles and slows down under my weight. I've been trying to fix the board for weeks, but maybe the problem actually comes from the motor. Did you test it with another motor? I took my motor apart and the magnets still feel strong.

Le sujet ayant été déplacé, je republie le contexte : je possède un tapis de course ProForm Endurance S7.5 d'occasion. Il présente un problème : la bande de roulement tourne, mais manque de puissance ; lorsque je monte dessus, il ralentit.

Lorsque je mesure le courant au niveau du moteur, même à vitesse maximale, il reste bloqué à 1,25 A. La tension monte correctement à 130 V à 18 km/h. À 4 km/h à vide, j'obtiens 28 V et 0,09 A, et lorsque j'accélère, le courant passe à 0,20 A. La résistance du moteur est de 1,2 ohm, ce qui semble correct.

La LED rouge sur la carte de contrôle clignote, et j'ai déjà testé le capteur de vitesse, qui fonctionne correctement.

Auriez-vous une idée ou une piste concernant la cause de ce problème ? Merci !

Since the topic has been moved, I am reposting the context: I own a used ProForm Endurance S7.5 treadmill. It has an issue: the running belt moves, but it lacks power—it slows down when I step onto it.

When I measure the current at the motor, it remains stuck at 1.25 A, even at maximum speed. The voltage rises correctly to 130 V at 18 km/h. At 4 km/h (with no load), I get 28 V and 0.09 A; as I increase the speed, the current rises to 0.20 A. The motor resistance is 1.2 ohms, which seems correct.

The red LED on the control board is flashing, and I have already tested the speed sensor, which is working properly.

Do you have any ideas or leads as to what might be causing this problem? Thanks!

Sorry, I made a bad copy-paste.

Since the topic was moved, I'm re-posting the context: I have a ProForm Endurance S7.5 treadmill that I bought second-hand. It has an issue: the belt runs, but it lacks torque—when I get on it, it slows down.

When I measure the current at the motor, even at max speed, it stays stuck at 1.25A. The voltage scales up properly to 130V at 18 km/h. At 4 km/h empty, I get 28V and 0.09A, and when I step on it, it goes up to 0.20A. The motor resistance is 1.2 Ohms, so that seems OK.

The red LED on the control board is flashing, and I've already tested the speed sensor, which is working fine.

Do you have any ideas or leads on what might be causing this? Thanks

It appears to be a variation of the 2100 versions?
Have you reffered to the schematic posted previously?
Does it have a similar model No. on the board?
Check the devices in the HV DC power string.

(OK I see MC2100ELS in the desc)!

The motor runs, but it lacks power/torque. Could this be an issue with the high-voltage side? As a beginner, my line of thinking was that if the motor runs, the power section must be working, and the problem might instead lie with the regulation or control system.
