Connection for 6-Lead Motors They have two configurations available for high speed or high torque operation. Higher speed configuration(also named half coil), it uses half of the motor's inductor windings. Higher torque configuration(also named full coil), it uses the full windings of the phases. ![]() | ![]() |
