Understanding AC Gear Motor Design

Sinotech    December 21, 2012

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

Sinotech   

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…

Top Benefits of the Brushless DC Motor (BLDC Motor) System

Sinotech    November 28, 2012

The brushless DC motor is quickly gaining popularity across several industries. BLDC motor design houses don’t use brushes for commutation; they use electricity instead. From the aerospace industry to home entertainment, brushless DC motor manufacturers tout the following benefits over brush motors in motion-control applications: Durability – a brushless DC motor can last much longer. Higher efficiency and less wasted heat. Lighter in weight. Available in compact sizes. Simpler to maintain. Less noise produced. Inexpensive to manufacture. More reliable. BLDC motor design houses contaminate the components less. Good for use in smaller devices. No commutators used. It’s simpler for the…
