New Industrial Servo Motor Yaskawa AC Servo Motor InsF 46.9A SGMG-60A6B-TK11

Efficiency - The ratio or comparison of power output to power input. End Bell / End Shield - The plates at each end of the motor which support the bearings. End Play - This term refers to the in and out movement the rotor has in the motor. Excessive end play can result in problems such as fan blades hitting the fan guards. No end play can result in a tight motor. Fractional Horsepower - Horsepower less than 1. Frame or Frame Size - A designation that controls certain specifications that a motor will be built to if it is to be called a particular frame size. Specifications such as motor diameter are controlled. Free Air - The blower or fan blade operates at free air when there are no effective restrictions to air flow at the outlet or inlet. Full Load Torque - This is the amount of torque produced by a motor when it is running a full load speed at rated horsepower. Full Load Amps - Amperage drawn by a motor when operating at rated load, voltage, and frequency. General Purpose Motor - It is designed with standard operating characteristics and mechanical construction for use under usual service conditions. Has a service factor rating. Grounding - The connection of a motor to an earth ground to reduce the possibility of electrical shock. Heating Degree Days - Each degree that the average temperature is below 65 degrees F produces one heating degree day.

Hertz - Frequency in cycles per second of an AC power supply. The U.S. operates on 60 hertz (HZ). Hi Pot (High Potential) - This is a motor test used to detect conditions where electrical conductors (IE lead wires, magnet wire) may have come in contact with the non-electrical parts of the motor (IE stator laminations, shell). Horsepower - The rating of a motor’s ability to do work. HP = watts output / 746. HP = (RPM x Torque in ounce-inches) / 1,000,000. One HP = 746 watts.
