The AND screwdriver is distinguished between handheld and machine-mounted models of the same power. The machine-mounted model adopts an aluminum alloy metallurgical structure to ensure that it meets the high-frequency locking requirements under machine automation. Japanese electric motors feature high reliability, strong performance, high precision and long service life. AND uses industrial-grade motors, while other brands use commercial-grade motors. Permanent magnet servo motors have strong physical capabilities and can output high torque at low speeds. It adopts F-grade enameled wire and can withstand high temperatures up to 133 degrees. High-density silicon steel sheets have better heat dissipation. Precision control (torque, speed, Angle), data management (traceable, exportable, uploadable to MES system), support for RS232/485 Modbus RTU communication protocols, support for high-speed Ethernet access, strong scalability, and support for multiple IO input/output channels.
