Gearmotor Selection and Application Guide
We review the construction, operating variables, and different types of fractional horsepower (FHP) “integral” gearmotors. Some of the topics covered in this guide are: gearmotor mounting orientation, impact of lubricant on gearhead life, duty cycle considerations, gearhead efficiency and noise, gearhead life, Brush life, ambient temperature…
AC Inverters (VFDs) For Variable Speed Applications
在线看黄av免费Inverter drives (also called variable frequency drives) allow AC inverter-duty gearmotors and motors to run at variable speeds. The DC voltage is “chopped” by power transistors (IGBTs) at high frequencies to simulate a sine wave that is then sent to the motor. Varying the output voltage and frequency of the control changes the speed of the motor...
Benefits of Hypoid Gearmotors
Right angle gearmotors with hypoid gearsets have several advantages when compared with standard worm-and-pinon right-angle gearmotors. Hypoid gearmotors are more efficient, produce less heat, provide higher torque, and are usually smaller than equivalent gearmotors with worm-and-pinion reducers.

This application note explains the steps to properly wire our standard 34B/SR-WX, 12/24VDC gearmotors for remote operation in a non-hazardous location...
Safe Operating Area (SOA) Ratings of AC Inverter Duty Gearmotors Explained
We define SOA Torque as the maximum torque at which the motor still operates within Class F thermal limits, or as the maximum torque of a gearmotor when it is gear-limited. Continuous duty operation must be limited to the area below the SOA or gear-limited torque curves. The SOA speed of our inverter-duty non-synchronous AC 3-phase motors and gearmotors is...
Introduction to Planetary Gearmotors
Planetary gearheads are typically comprised of a sun gear, a ring gear, and a planet carrier assembly with three to five planet gears per stage. Planetary gear trains are popular in applications where more torque is required from a smaller gearmotor package.
What is a Synchronous AC Motor?
The difference between the speed of the rotating magnetic field of an induction motor (which is always synchronous) and the speed of the rotor is known as "slip". When the rotor design enables it to "lock into step" with the field, the slip is reduced to...
Introduction To Worm Gearing
