811 SERIES motor produces almost no noise, saves energy (60-80%) and is brushless, speed djustable and durable. It provides a high starting torque even at low speed or from a complete stop. The motor can be set to rotate at different maximum speeds, in either normal or reverse directions, and can start with different accelerating speeds. It will stop automatically with any interruption such as in-age, electrical surge, radio frequency interference or overloading. It is fully protected by the software and will give error messages indicating which problem is encountered. It even works well in environments with an unstable electrical power supply.
