This frequency converter can be used for loads with constant torque (e.g., hard starts: air compressors, HVAC units) and loads with variable torque (e.g., pumps, fans, etc.). It can be used as a motor speed controller and phase converter. Many customers have purchased this spindle motor from us for use in lathes, mills, car lifts, pumps, conveyors, etc., and have achieved excellent performance.

• 【PRODUCT DETAILS】 - The air-cooled 3 kW spindle motor has a speed range of 0-18,000 RPM, a frequency of 300 Hz, and a runout error of less than 0.005 mm. The 4 HP 3 kW frequency inverter uses PID control, advanced PID calculation with controlled loop, and offers fast response speed and high suitability.
• 【EXCELLENT QUALITY】 - The spindle motor uses bearings imported from Germany. The spindle motor itself is also made of high-quality materials. This results in stable performance, ease of use, high quality, low noise, and more.
• 【HIGH PERFORMANCE】 - The frequency inverter reacts quickly and is highly suitable due to its advanced closed-loop PID calculation. Furthermore, it features a low output tapping torque of 0.5 Hz - 150% and a low operating speed.
• 【IMPROVED PROTECTION SYSTEM】 - The frequency inverter is perfectly protected against faults and short circuits, reducing machine damage and extending the product's lifespan. It offers you excellent safety performance.
• 【COOPERATION】 - The air-cooled spindle and the frequency converter are definitely a good combination to improve the work efficiency and performance of the frequency converter.
