Study Notes
Philippine Agricultural Engineering Standards (PAES)
- PAES stands for Philippine Agricultural Engineering Standards
- There are 13 volumes of PAES
- PAES has 5 machine categories
- There are 271 PAES standards
Agricultural Tractors
- PAES 109:2000 specifies requirements for walking-type agricultural tractor classified as pull-type
- PAES 110:2001 specifies minimum requirements for walking-type agricultural tractor classified as rotary tilling-type
- PAES 111:2000 specifies methods of test and inspection for walking-type agricultural tractor
Agricultural Machinery Testing and Evaluation Center (AMTEC)
- AMTEC stands for Agricultural Machinery Testing and Evaluation Center
Walking-Type Agricultural Tractor (WTAT)
- Parts of pull-type WTAT include human power, which is a poor source of power (0.1hp under favorable conditions)
- A person can cultivate only 1 ha of land using hand tools
Draft Animals
- In 1976, the population reduction of draft animals in the Philippines was caused by hoof and mouth disease
- The optimal draft power of a carabao is 15% of its total weight
Electric Motors
- Electric motors are commonly used as stationary prime movers for processing farm products and by-products
- Alternating current (AC) motors use an electric current that reverses its direction at regular intervals
- Service factor indicates the maximum load that can be successfully carried by the motor if operated continuously
- Open type enclosure is used in electric motors to allow easy movement of air in and out of the windings
DC Motors
- The commutator is an electric motor part only found in DC motors, which overturns the direction of electric current
- Field pole is the interaction of two magnetic fields that causes rotation in a DC motor
- Armature becomes electromagnetic when current goes through it
Internal Combustion Engine
- It is a type of heat engine where fuel is ignited and burned inside the cylinder
- Internal combustion engine has parts such as piston, piston rings, piston pin, connecting rod, bore, and auxiliary parts and accessories
Induction Motor
- It is the most popular motor in industry due to its ruggedness and lower maintenance requirements
- The two main electrical components of induction motor are rotor and stator
