Amperage The amps that the unit is designed to operate at.	1.7 Amps

Speed(s) The number of speeds a motor runs at. Motors with 4 speeds can run at High, Medium High, Medium Low, and Low. Motors with 2 speeds can run at either high or low speed.	1

Service Factor A measure of reserve margin built into a motor. Motors greater than a 1.0 SF have more than normal margin, and are used where unusual conditions such as occasional low voltage, momentary overloads, ect. are likely to occur. Used in "heavy duty" applications.	1.0 SF

Horse Power The amount of power generated by the motor. One horsepower (HP) is equivalent to 746 watts.	1/4 HP

Revolutions Per Minute Rotational speed in revolutions per minute	1075 RPM

Bearing Basic types include: Sleeve - Preferred where low noise level is important, as on fan and blower motors. Unless otherwise stated, sleeve bearing motors listed can be mounted in any position, including shaft-up or shaft-down. Ball - Used where higher load capacity, either axial or radial, is required or where shaft speed is lower than 500 RPM. Shields, metal rings with close running clearance one one side (sigle-shielded) or both sides (double-shielded) of bearing, and seals, which are similar except with rubber lips that press against inner race, more effectively excluding dirt, ect., are two barriers used to keep out dirt.	Sleeve

Ambient The temperature of the space around motor. Measured in Celcius (40 degrees celcius equals 104 F).	60 Degree Celcius

Rotation	Reversible

Mounting Resilient Mounting - Sometimes called rubber or hub mounted - motor shell is isolated from base by vibration absorbing material, such as rubber rings on the end shields, to reduce transmission of vibration to the housing of the unit or appliance. Stud Mounting - Motor has bolts extending from from front or rear, by which it is mounted. Often used on small, direct drive fans and blowers.	Hub/Stud

Replaces Type of motor this model replaces.	1075 RPM 1/4 H.P. Condenser Fan Motors

Shaft Dimensions Width of the shaft (usually 1/2") x the Length of the shaft.	1/2 x 5 Inches

Thermal Overload Protection A temperature or current sensing device usually integral within the motor, that disconnects the motor winding from its power source to prevent overheating due to overload or failure to start. Automatic Reset(Auto) - After Motor cools, protector automatically restores power. Should not be used where unexpected restarting would be hazardous.	Auto

Total Length Total length of motor and shaft.	9.9 inches

Voltage	208 / 230 Volts

Frequency	60 Hz
