The DFA68 and DFA90 series brushless dc motors from Nanotec are now available with integrated encoder. Their extremely compact design makes the new external rotor motors particularly suitable for applications that require precise positioning in confined spaces, such as AGV wheel drives, access control gates and door drives.
Both motors are equipped with a 3-channel encoder and have a resolution of 4,096 CPR. Field-oriented torque, speed and position control – together with the integrated encoder – ensures optimal dynamic performance. The inductive scanning principle, which is insensitive to magnetic interference, made it possible to integrate the encoder directly into the motor and restrict the installation length to just 42 mm.
The DFA90-E with a diameter of 90 mm has a rated power of 168 W at a rated speed of 2,000 rpm. The smaller DFA68-E with a diameter of 68 mm achieves 106 W at a rated speed of 3,500 rpm. Due to their high pole construction the motors also run quietly at low speeds.
In addition to the standard versions, custom windings or shaft modifications are also possible.
