Foreword

SVD48V series in-wheel motor servo driver is a one-to-two low-voltage motor drive product

launched by UU Motor Technology Co., Limited. This series can adapt to two 100W~800W in-wheel
motors at the same time, adopts FOC drive mode with encoder, supports optical encoder with Hall,
and magnetic encoder solution. The driver has RS485, RS232 , CAN communication interface, and

PWM or pulse input, they can all control the motor operation. Using RS485 or CAN bus can realize

the parallel operation of multiple drives, which is suitable for two-wheel or multi-wheel drive platform.
The driver adopts a single control chip to achieve one-to-two, so that the two motors driven have better speed
synchronization, and fault protection is more timely and reliable, especially suitable for two-wheel-drive

AGV platforms.

SV-Config for this series The PC -side host computer debugging software provides parameter

list setting and real-time waveform display interface, which is convenient for setting various parameters,
and can also test the performance of the driver and motor in real time, providing very friendly help for

parameter adaptation.
