Gear motors, in general, are rigorous and sturdy pieces of mechanical device. But if you are specifically after optimal performance, using an integrated ac motor is highly recommended. This is the key reason why many have been switching to the use of this fully integrated gear motor. Thanks to the low-inertia of the motor’s rotor that is specially designed to match the characteristics of the gear unit. As a result, the gearing system has high dynamic capacity which is best suited for instant stop-and-start gear applications. Most of them even have high-performance brake which is perfect for use when controlled load deceleration is highly required.
Another great benefit of using ac motor is its compatibility with inverters. The use of a good combination of this gear motor and a VFD, variable frequency drive, gives birth to the possibility of indexing as well as point to point positioning gear applications. These drives are also good at making fine-tuning of control and speed easily and more efficiently. They can be equipped with various features to provide such functions, including adjustable starting torques and protection from overloading. Taking those advanced qualities of an ac motor aside, its biggest strength in terms of performance lies in the fact that it offers endless possibilities for combinations of motor and gear unit.
However, you still have some important things to keep in mind when determining the efficiency of the motor drive system you need. You have to consider a number of factors, which includes gearbox loading, input and output power to the gearbox or the speed and load torque required. The efficiency, basically, is the ratio of the output power to the input power needed by the gearbox. So, you have to pay attention to these things whenever you’re looking for an ac gear motor for specific application.
