Speed sensor for e-bikes gives data to adjust motor performance 

A compact e-bike speed sensor from ZF provides the necessary data to adjust the performance support of the motor to the speed.

The sensors are based on the principle of Hall-effect and they are non-contact and durable. In combination with ferromagnetic target wheels, a high-resolution speed measurement with over 50 pulses per revolution can be implemented. 

The overall system of the ZF hall sensor with speed disc offers considerable benefits  to the functional safety, the manipulation safety and the response of the e-bike engine in comparison to the conventional reed systems with external magnet, claimed ZF. Therefore, the ZF e-bike sensor is also suitable for ABS systems, which are experiencing an increasing demand within the e-bike industry.   

The GS82-AA06 sensor measures 21.75mm in length and 9.35mm in diameter. As an interface to the drive system, the Higo connector has a cross-section of only 0.14mm² and due to its small size is prevalent in the e-bike industry. Depending on the customer’s requirements the contact via connector, as well as the cable length, can be preselected individually. The sensor requires a constant voltage supply of 6.5Vdc to 20Vdc and measures frequencies between 1Hz and 2,500Hz. It is designed for a temperature range from -25 degrees C to + 85 degrees C.

ZF supplies systems for passenger cars, commercial vehicles and industrial technology, enabling the next generation of mobility. In the four technology domains of vehicle motion control, integrated safety, automated driving and electric mobility ZF offers comprehensive product and software solutions for established vehicle manufacturers and newly emerging transport and mobility service providers. ZF electrifies a wide range of vehicle types. The company’s products contribute to reducing emissions, protecting the climate and enhancing safe mobility.
