Key Features Strong and Durable: The housing of this product is made of high-quality aluminum alloy, which is strong, durable, wear-resistant, anti-shock, high-temperature resistant, and can protect the internal parts well. Stable Operation: Both ends of the speed control motor rotor are fitted with ball bearings, which allow it to operate with low friction, reduce energy consumption and generate lower temperatures to ensure stable operation. High Efficiency: The stator and rotor are made of pure copper coils with good electrical conductivity, allowing for a constant high and stable power output. Adopting high-precision steel gears effectively increases the torque of the motor, which greatly enhances its working efficiency. Adjustable Speed: You can adjust the speed from 0% to 100% through the stepless speed knob on the governor according to the different situations to achieve the desired effect. Easy to Install: Since the motor and gearbox are already installed, you only need to plug the governor cable into the jack of the motor cable to quickly connect the motor and governor. Forward and Reverse Rotatable: The governor is initially specified for forward rotation, but you can connect the wires on the CCW to the CW and then it can be converted to reverse rotation to suit your different needs. Good Heat Dissipation Performance: The motor has a built-in fan heatsink and cooling holes at the rear of the motor, providing good ventilation and heat dissipation to ensure stable performance. Application This product is widely used in industrial assembly lines, intelligent equipment, animal husbandry machinery, printing machinery, textile machinery, instrumentation, power transmission and transformation equipment, road gate machines, logistics equipment, security check facilities, new energy, industrial robots, and other industries.
