DM GBD Series Motors with Encoder and Driver
DM and RMD series motors are same, but different in driver. DM driver is compatible with Alexmos SimpleBGC, the user can use Alexmos SimpleBGC controller to control the motor. RMD driver is open RS485 protocol, the user can design his own controller to control the motor. RMD series are divided into RMD-S (Starter version) and RMD-L (high Level).
