1. It is according to current driver’s dimensions, to optimize the design, integrated the soft start motor, reducer and the brake. Thereby improved the installation quality, reduced the assembly time, optimized installation program.Integration driver is with small size, light weight, easy installation and easy-maintenance, compact and beautiful structure.
2. This series soft start driver is equipped with YSE series dual-rotor soft start 3 phase asynchronous brake motor. F-class insulation, IP54 protection class. Motor housing is aluminum alloy, reduced weight and helped motor heat dissipation. So it prevents the motor winding aging easily, extends the lifespan of the motor. Motor adopts cold-rolled silicon steel sheet, (which) enhances the output power, the motor heat condition,starting torque performance.It is much better than hot-rolled silicon steel sheet.
