How to choose the right motor power for the RF97-Y3-4P-30.56-M1-0° reducer?

When selecting the appropriate motor power for RF97-Y3-4P-30.56-M1-0 ° reducer, the following aspects need to be considered:

Calculate load torque

Determine workload: Conduct a detailed analysis of the working conditions of the equipment driven by the reducer, including the nature of the load (such as constant torque load, variable torque load), operating mode (continuous operation, intermittent operation), and whether there is any impact load. For example, for conveyor belts, factors such as the weight of the conveyed material, the speed of the conveyor belt, and the frictional resistance of the transmission mechanism should be considered; For a mixer, it is necessary to consider the viscosity of the mixed material, the size and speed of the mixing blade, etc.

Calculate load torque: Based on the working load of the equipment, calculate the load torque using the corresponding formula. For some common devices, there are empirical formulas available for reference. For a conveyor belt, the load torque T=F × D/2, where F is the traction force of the conveyor belt and D is the diameter of the driving drum. When calculating, a certain safety factor needs to be considered to ensure that the gearbox and motor have sufficient load-bearing capacity during actual operation. Generally speaking, for steady loads, the safety factor can be taken as 1.2-1.5; For situations with impact loads, the safety factor can be set at 1.5-2.5 or even higher.

Consider the efficiency of the gearbox

Efficiency factor of reducer: The reducer will experience certain energy loss during the transmission of power, and its efficiency will affect the selection of motor power. The efficiency of RF97 gearbox is usually between 0.8-0.95, and specific values can refer to the technical data provided by the gearbox manufacturer. Generally speaking, the larger the transmission ratio, the slightly lower the efficiency may be; The larger the load, the higher the efficiency.

Efficiency calculation and power correction: When selecting motor power, it is necessary to correct the load torque based on the efficiency of the reducer. The output power of the motor is P=T × n/(9550 × η), where T is the load torque, n is the motor speed, and η is the efficiency of the gearbox. For example, if the load torque is calculated to be 100N · m, the motor speed is 1500r/min, and the reducer efficiency is 0.9, then the motor power P=100 × 1500/(9550 × 0.9) ≈ 17.5kW.

Combining with actual working conditions

Environmental conditions: Consider factors such as temperature, humidity, altitude, etc. that affect the operation of the equipment. If the ambient temperature is high, the heat dissipation conditions of the motor will deteriorate, and it is necessary to reduce the power consumption of the motor appropriately to prevent overheating. Generally speaking, for every 10 ℃ increase in ambient temperature, the motor power needs to be reduced by 5% -10%. If the altitude exceeds 1000m, the thin air will affect the heat dissipation and insulation performance of the motor, and the motor power also needs to be corrected.
