high power vs low power dc motors
At 6V the ''low power'' motor draws 0.25A free running and 2.4A when stalled, so its power consumption ranges from 6x0.25 = 1.5W to 6x2.4 = 14.4W. The ''high power'' motor draws from 3.3W to 39W. So the ''high power''

Could A Low Battery Cause Loss Of Power? Effects On Engine
When the battery voltage drops, it cannot supply enough power. This affects the starter motor''s ability to turn the engine over effectively. Using high-quality batteries can reduce the frequency of low battery power issues. High-quality batteries are more resilient to wear and can hold a charge longer. Research by Consumer Reports
lithium ion
The first on will be ~1.3-1.5 kW, 24 V motor (7s21700 battery). The second will be a 10 kW, 72 V (20s21700 battery) motor. So the 4.2-2.5 V swing per cell is going to put me outside my acceptable voltage range on both projects. I could limit the charge/discharge voltages but that would just suck because I don''t want to lose that storage.

High Power Very Low Voltage Electric Motor for Electric Vehicle
However, for many applications where the power is relatively low (< 30 kW per motor), it can be more beneficial to size the system at very low voltage (< 60 V).
How do I determine if a battery will adequately power an electric motor
$begingroup$ Battery Watthours = Vbat x Ahcap = 3.2V x 160Ah = 512 Wh. Motor power = 8200 Watts nominal. Ignoring voltages - battery energy is enough at 100% drain at 100 % efficiency to run motor at fill power for Battery_energy Wh / Motor power W = 512/8200 H = 0.06H = 3.75 minutes.

Motor Mover / Battery Query
If the battery is good, it should drop to 12v and recover almost immediately. If it is shot, it will drop and stay down, possibly as low as 2v . The mover must have a full 12v minimum to work, any less and it will not. As you say the battery is 3 months old, if you have the receipt I am guessing it is still under warranty.

It is a battery powered application so energy efficiency is important as is low speed control down to 10-20 RPM. Encoders are fine but an encoderless solution would be great.
Does more "Power" (W) means better motor?
The wattage rating is usually (read the manufacturer''s specs very carefully) the measure of how much power the motor can draw. It doesn''t tell you anything more than that. Wattage does not tell you whether the motor is efficient at converting the input electrical energy into output mechanical energy.. Wattage does not tell you whether the motor''s power-to
How to use AA batteries to power a 12V 30W motor :
Hi all, I have a 12V motor 30 Watts, and I want to power it using a bunch of Duracell AA batteries either in series or parallel or whatever it needs. You will need to take many of those 8 battery series sets and put them in parallel to get enough current. Google says that each aa battery can output about .05A. ESP32 is a series of low

Is a Hi-Watt 9V battery enough to power two DC motors
The vehicle is powered by two basic DC motors that are connected with an H-bridge and they are powered by one Hi-Watt, 9V battery. another Hi-Watt, 9V battery is powering the arduino that run the code of the car. My question is : can this 9V battery power two motors simultanuously, if not should I put two batteries in series or in parallel?

6 FAQs about [High power battery puts low power motor]
What voltage should a motor battery be used for?
For low power applications (< 30 kW per motor),\ it can be more beneficial to size the system at very low voltages (< 60 V). However, under certain conditions, the voltage chosen for the battery in other applications can be very high, going up to 700 V, to simplify the motor electrical supply system by reducing the current levels.
Which motor is best for a battery-powered application?
One key motor performance parameter to consider in a battery-powered application is efficiency. Maximizing motor efficiency helps minimize the required power capacity and hence the size and cost of the battery solution. For this reason, brushless DC (BLDC) motors are preferred over brushed DC motors but are typically higher in price.
Does a car battery have a high current?
A car battery is low voltage (low water pressure) and capable of high current (high water flow rate). However it doesn't matter that the car battery is capable of delivering high current it lacks the pressure to "push" high current through.
What voltage should a battery be?
According to the 2014/35/UE European Directive for the CE marking, the voltage level for a High Power Very Low Voltage Electric Motor for an Electric Vehicle should be 75 V DC. The standards dealing with very low voltage systems (VLV) provide this general guidance.
How does battery voltage affect motor speed?
Batteries also see a decrease in terminal voltage as the output current (load) increases, which also negatively impacts motor speeds at higher torque loads. These factors do not consider the characteristics of the motor winding itself, where output speed decreases as the motor load increases, even with constant battery voltage (see Graph 1, below).
Why does a motor have a high current?
The question is in load resistance. When you connect your motor, you only draw a certain amount of current, because motor has resistance. So the current is 12V/Rload=Iload (or any other load). So your current very much finite and limited. When you just short + with -, you connect close to zero resistance, which causes very high current.
