For a scissor lift, I need around +-102Watt to lift it, and while at lowest position before lifitng, it is around 9.08Nm torque required, and at highest position the speed is fastest where,447.8RPM.Now i do not know how to choose a DC motor and gear reduction ratio. because i cannot search any 120 watt catalogue have 10Nm stall torque. Can anyoe have any idea? or can we gear the motor torque over the motor stall torque at gearbox output? Thanks ...please help, and also the torque at output of gear box is gradually reducing,so RPM increasing? So what should be the ratio reduction of gear? From input motor speed to gear output speed..Which output speed location should i choose? Thanks
