Product Description

Products Details

Z series motors are all equipped with compensation windings, which can provide good commutation function. F-class insulation motors have reliable insulation structure, adopt vacuum pressure impregnation process, solvent-free impregnation, stable insulation and good heat dissipation. It can be powered by DC unit power supply or static rectifier power supply, with small rotational inertia, good dynamic performance, and high load change rate. It is particularly suitable for control systems that require smooth speed regulation, high efficiency, automatic speed stabilization, and sensitive response.
This series of motors can be powered by DC power supply or static rectifier power supply, with small rotational inertia, good dynamic performance, and can withstand high load change rate.
