What is a torque sensor on an ebike?
What is a torque sensor on an ebike?
A torque sensor measures how hard the rider is pedaling to determine how much electric power to push to the bike. The harder you pedal, the more power it gives to the motor. If you pedal lighter, less power goes to the motor.
How does a steering torque sensor work?
Function of the torque sensor The sensor sits on the steering pinion. When the driver applies torque to the steering wheel, the torsion bar is rotated and, in turn, the magnet relative to the sensor. The sensor consists of magnetoresistive elements whose resistance changes as the field direction changes.
What is torque angle sensor?
Torque and angle sensors measure steering wheel position and torque applied by the driver on the steering wheel. These signals are then fed to the transmission Electronic Control Unit (Transmission ECU). ECU gives respective signals to the steering drive to apply desired torque.
How is ebike torque calculated?
Electric Bicycle Glossary
- Watts: A measure of power, 745.7 watts is equal to 1 horse power.
- Power: More power gives you a higher top speed.
- RPM: Revolutions per minute.
- Torque: Torque = Force x Distance, torque is the ability of the motor or rider to rotate a wheel; higher torque gives faster acceleration.
Is torque sensor better than cadence sensor?
With a torque sensor in use, the electric bike’s motor will increase its output relative to the amount of pedal force the rider is applying. A torque-based PAS may also engage relatively more quickly than a cadence-based PAS. And on some models, using only a torque-based PAS may increase range.
What is the difference between a speed sensor and a cadence sensor?
The speed-only sensor determines the speed and distance of a trip based on the wheel circumference of a bike. The cadence-only sensor only senses rotations per minute of the crank arm. The speed/cadence combo is the most popular, providing both types of data to cyclists through a combination of sensors.
What sensors are needed for EPS systems?
Generally speaking, an EPS system consists of three different sensors:
- The steering wheel position sensor, which derives the absolute position of the steering wheel.
- The steering torque sensor, which converts torque applied to the steering wheel by the driver into an electrical signal for processing.
What is good torque for an ebike?
Most ebikes have around 50 or 60 newton-metres of torque, while some deliver 80 or 85 newton-metres of torque. The more newton-metres of torque your motor can produce, the less hard your legs have to work to turn the pedals on your bike.

How much torque should an ebike have?
What is a torque sensor on an electric bike?
Torque Sensors on Electric Bikes. A torque sensor is a type of throttle that determines how much juice to feed the motor based on how hard the rider is pedaling. This is different from a cadence sensor which measures simply how fast you are pedaling.
How does an e-bike work?
Maintenance-free On an e-bike, the applied pedaling torque of the rider is measured by the torque sensor and sent to the controller of the e-bike along with cadence information. Based on this information an algorithm controls the motor speed and power.
What is the torque sensor on a servolectric electric power steering system?
The torque sensor in the Servolectric® electric power steering system measures the torque the driver applies to the steering wheel. Based on this data, the electronic control unit calculates the steering assistance which the electric motor needs to apply. 0,015 Nm
Why can’t we use optical sensors in electric bikes?
Optical sensors are always susceptible to contamination on the lenses etc. This makes the optical principle less useful in an e-bike torque sensor application. Grease and oil are used in the motor unit, and for the cranks and bearings in the exact area where the sensor is placed.
