I am looking for a motor with the following characteristics:
• Cheap
• Easy to control
• Can provide 150-200 grams’ thrust
• Weighs less than 50 grams
• Low voltage: (preferably under 12 V ideally 5 V)
I am using the following equation to calculate thrust
T=100*(nb 2 Pi Rho (P^(2)) (R^(2)))^(1/3) [gf]
nb=0.75
P=VI=torque*rotational velocity [w]
R=0.066[m]
rho=1.22[kg/m3]
Is this calculation viable?
Does such motor exist?
Do I use coreless brushed motor, or brushless motor?
Voltage specification: I set the voltage low because I thought that a higher voltage would demand a heavier battery, such to lower the overall weight I thought to limit the voltage on the motor, is this a stupid assumption?
Thank you
