· Motor Size

· Horsepower

· Measure of power needed to move 550 ft/lbs per second for 8 hours

· 1 HP = 550 lb * 1 ft/sec

· 1 HP = 5252 lbs-ft* rpm

· kW

· 1 HP=746 watts (100%) efficiency

· FLA

· Full load ampere (FLA) ratings of motors vary on several factors:

· Average values listed in the National Electric Code (NEC) should only be used as a guide for selecting components for the motor branch circuit

· The rated full load current shown on the motor nameplate should always be used if known

· Control Voltage

· 120v                 60Hz

· 24v                    60Hz       

· 24v                    DC

· 115v                 50Hz

 

Reduced Voltage & Solid State Starters Starter Standard Duty Ratings

· Combination or Non-Combination Starters

· Starters can start, stop, forward/reverse, provide multi-speed, and protect a motor

· Starters are made from two building blocks:

· Contactors: control the electric current to the motor.  Their function is to repeatedly establish and interrupt an electrical power circuit

· Overload protection: protects motors from drawing too much current and overloading

· Electronic overloads protect from phase loss, phase imbalance, and are ambient compensated

· Combination starter includes:

· Motor disconnect function

· Magnetic short circuit protection

· These capabilities come from the following combined devices:

· Disconnect

· Disconnect with fuses

· Motor circuit protector

· Single Starter or Multiple Starters

· Advantages of Building Multiple Starter Panels

· Starters are made from two building blocks:

· Cost savings—one enclosure

· One incoming electric feed

· Interconnection wiring allowing better process control

· Operator safety—one handle disconnects all power

· Full Voltage-Non-Reversing (FVNR)

· Most commonly used general purpose starter

· Connects the incoming power directly to the motor

· Can be used in any application where the motor runs in only one direction, at any one speed, and starting the motor directly across the line does not create any dips in the power supply

· Reduced Voltage

· Typically used in applications involving large HP motors or small motors on generator service

· Used to reduce the inrush current and limit torque output and mechanical stress on load

· Types:

· Auto Transformer

· Wye Delta

· Solid State

 

Reduced Voltage & Solid State Starters Starter Standard Duty Ratings

· Soft Starters Considerations

· How often will the motor be started?

· Does the enclosure allow ventilation?

· What ramp time is required?

 

· Solid State Soft Start

· S801/S811 Eaton Soft Start Provides:

· Reduced wear and tear on belts, gears, shafts, and bearings
