Resistance motors for fitness equipment
A resistance motor adjusts the training resistance of compatible fitness equipment. Does the resistance no longer change, stay at one level or make an unusual noise when adjusted? The resistance motor may need replacing. Always check the brand, full model, version and part number before ordering.
What does a resistance motor do?
On fitness equipment with electronically adjustable magnetic resistance, the resistance motor moves the adjustment mechanism at the brake or magnet. When you select a higher or lower resistance level on the console, the electronics activate the motor. The distance from the flywheel or the position of the braking mechanism then changes, making the workout easier or harder.
Which fitness machines use a resistance motor?
Resistance motors are used in exercise bikes, cross trainers, rowing machines and other equipment with electronically controlled resistance. Not every fitness machine uses this type of motor. Machines with manually adjustable resistance, for example, often use a mechanical dial and a tension cable.
Is a resistance motor the same as a drive motor?
No. A resistance motor is a relatively compact component that adjusts the resistance system. A drive motor provides the movement itself, such as the motor that drives the running belt on an electric treadmill. These components serve different functions and are not interchangeable.
How can you recognise a potentially faulty resistance motor?
Possible symptoms include resistance that no longer changes, a mechanism stuck in one position or repeated clicking or rattling during adjustment. Sometimes the level shown on the display changes while the actual training load stays the same. However, these symptoms may also be caused by wiring, a loose adjustment mechanism, the console or the mainboard.
How do you find the right resistance motor?
Where possible, search using the exact part number from your fitness machine’s technical documentation. Also check the full model name, serial number and, where relevant, year of manufacture. Different versions of the same machine may have a different motor, connector, cable, direction of rotation or adjustment setting.
Do not compare resistance motors solely by their appearance. Even when the housing and connection match, the internal gearing, operating angle and electrical specifications may differ.
Replacing a resistance motor safely
Switch the fitness machine off completely and unplug it from the mains before opening the housing. Before dismantling anything, record how the wiring and adjustment mechanism are connected. On some machines, the new motor must be installed in a specific starting position or calibrated after installation. Follow the technical instructions for the machine concerned or have the repair carried out by someone with sufficient experience.
