• The speed is based on the synchronous motor speed reduction ratio as a benchmark calculated by dividing the value of.Actual speed will vary the size of the load changes in less than the values shown in2~15%.
• Hope to the table of the reduction ratio is greater than the further reduction,it would be installed between the motor and the reducer reduction ratiio of 10 the middle of the reducer.
• When the load torque exceeds the maximum allowable load torque gear motor,and a locked rotor situation exists,please slow down box at the junction of the output shaft and load torque limit device installed to ensure the normal operation gearbox.

Product Overview

The Small AC Gear Reducer Motor 90W is a 5RK series geared motor on a 90 mm frame, designed for higher-torque output in demanding machines. It delivers rated torque from 544 to 910 mN·m at 1350–1550 r/min across the 90–120W power range. Compared with the 40W and 60W units in the same frame, this model offers substantially more torque while keeping a compact, easily mounted package that suits retrofits and new builds alike.

Key Features

• Heavy-duty 90 mm frame with reinforced gearbox housing
• Reversible 30-minute rated duty for forward and reverse operation
• Single-phase 110V/220V and three-phase 380V options at 50/60Hz
• Rated torque 544–910 mN·m at 1350–1550 r/min
• Gear ratios from 3:1 to 500:1, maximum allowable load up to 19.6 N·m (200 kg·cm)
• High torque density for compact installations

Applications

The 90W gear reducer motor fits medium-to-heavy duty equipment including conveyor drives, mixing and stirring machines, packaging and filling lines, agricultural machinery, and industrial feeders. Its high allowable load makes it a practical choice where equipment must start under load or run for long periods.
