The main structure of inverter motor: NdFeB rare earth permanent magnet synchronous motor inverter from coding. The motor speed can be precisely follow the input frequency changes and changes in the rotational speed when a significant change was constant torque. In power, the situation with the same speed compared to other commonly used motor starting inrush current and volume were minimal, but the torque is 2-3 times that of other motor and motor stall when long Barrier manufacturers, motor operating current will not rise. Thus lifting the brake lever can be very smooth, precise control of gate opening (or closing) took Barrier types, theory accurate to 1/1000 second, and never under any circumstances be damaged motor (not including overvoltage usage). Installation and commissioning of the sense in the coiled coil when the Barrier brand, allow enough length of wire to connect to the loop sensors, can guarantee with no joints. Good wound coil cable after cable must be made of tightly twisted leads form of barrier, it requires a minimum of 1 m twisted 20 times. Otherwise, no twisted pair output leads jamming will be introduced, so that the coil inductance value becomes unstable. Output lead length should not exceed 5 meters. Due to the sensitivity of the detection coil with increasing lead length decreases, so the length of lead cable as short as possible.
