AC gear motors are electric motors that use an alternating current. They generally have two parts: the outside stationary stator and the inside rotor. Slip rings or a permanent magnet generate the magnetic field on the rotor. The stator has coils that receive an alternating current, which produces a magnetic field that rotates. An output shaft that’s attached the inside rotor of the AC gear motor acquires torque via the rotating field. The two most common types of AC gear motorsare synchronous and asynchronous motors. AC Synchronous Motors In synchronous motors, the rotation of the output shaft is synchronized with…
5 Great Tips for Working with Gearmotors
Whether you’re using a traditional model or a gearmotor with encoder, using it the right way will help extend its life and give you better results. The next time you work with a gearmotor, keep the following in mind: 1. Determine the required torque. When working with a gearmotor, including a reversible gearmotor, it’s important to consider the running and starting torque separately because the gearing and starting characteristics can differ. When determining the torque, the most important factors include the amount of work the gearmotor can do and its speed. 2. Consider an AC motor for optimal performance. When…
