Wet Grinders Power Consumption Calculator Kitchenarena
In the normal course, idli or dosa batter takes around 20 to 30 minutes for efficient grinding. However, you should not overload the machine or grind batter in low quantities. Overloading can tire the motor and lead to more power consumption. If you have less quantity to grind, your regular mixer grinder can do a good job.What I would do is that the motor out of the bent wheel and put into the new wheel and swap the noisy motor into the bent wheel. This is easy to do just remove the several screws/bolts holding the motor to the wheel hub. Usually these fasteners are located on the same side the motor cable goes into the motor.

How motors work and how to choose the right motor for any
Current is what powers the motor and too much current will damage the motor. For DC motors, operating and stall current are important. Operating current is the average amount of current the motor is expected to draw under typical torque. Stall current applies enough torque for the motor to run at stall speed, or 0RPM.5.3 GRINDING FORCES, POWER, AND SPECIFIC ENERGY. Forces are developed between the wheel and the workpiece owing to the grinding action. For plunge grinding operations, as illustrated in Figure 5-2 for straight surface and external cylindrical grinding, the total force vector exerted by the workpiece against the wheel can be separated into a 5.3: GRINDING FORCES, POWER, AND SPECIFIC ENERGY
