## MOTOR SIZING:

1 Dc motor and 1 Servo motor is required for our course project

### SERVO MOTOR:

Torque = F * r (In N-m) (SI UNIT) where F- Force acting on the body r- Lever arm length T- Torque

Volume of acrylic sheet=V= (18.50 x 10-6 ) m3(IN SI UNIT)

Mass of acrylic sheet=m= (21.830x 10-3 ) kg (IN SI UNIT)

Total mass= (60x10-3) kg (IN SI UNIT)

g= acceleration due to gravity (9.81 m/s^2)

F=mg=0.558 N (AS PER NEWTON'S SECOND LAW OF MOTION)

Torque without FS, T=2.354kg-cm

Factor of safety=1.5

Net torque, T=1.56 Kg- cm

Hence, we require a SG 90 Servo motor of 0.12 kg-cm torque

### DC MOTOR

Torque = F * r (In N-m) (SI UNIT) where F- Force acting on the body r- Lever arm length T- Torque

Volume of acrylic sheet=V= (2.7945 x 10-6 ) m3(IN SI UNIT)

r=4.5cm

Mass of acrylic sheet=m= (3.3254 x 10-3 ) kg (IN SI UNIT)

Total mass= (10x10-3) kg (IN SI UNIT)

g= acceleration due to gravity (9.81 m/s^2)

F= mg =10×10^(-3) 9.8 = 0.098 N (AS PER NEWTON'S SECOND LAW OF MOTION)

Torque without FS, T=0.441kg-cm)

Factor of safety=1.5

Net torque, T=0.294 Kg- cm

We require dc motor of 12V AND 300RPM
