DC geared motors with the controller, gear ratios from 3:1 to 200:1 available, rated at 3000 rpm, and designed to operate at 12V, 24V or 48V. The low-cost DC geared motor is a perfect solution to meet your application requirements.
The allowable torque with a gearbox
Tips: How to calculate the torque of a 300W brushless DC geared motor?
Gear reducer torque = 9550 * Motor power / Motor input rpm rated power * Ratio * Gear reducer efficiency. The calculation above is the torque equation. Motor power = Torque ÷ 9550 × Motor input speed at rated power / Ratio / Usage factor.
