For applications where adjustable speeds are essential, typically an AC electric motor with an Inverter or brush motors are used. Brushless DC motors are a sophisticated option due to their wide velocity range, low heat and maintenance-free procedure. Stepper Motors provide high torque and soft low speed operation.
Speed is typically managed by manual procedure on the driver or by an exterior change, or with an external 0~10 VDC. Rate control systems typically make 
use of gearheads to increase output torque. Gear types range from spur, worm or helical / hypoid based on torque demands and budgets.
Mounting configurations vary to based on space constraints or design of the application.
The drives are powerful and durable and feature a compact and lightweight design.
The compact design is manufactured possible through the combination of a spur/worm gear drive with motors optimized for performance. That is accomplished through the constant application of light weight aluminum die casting technology, which guarantees a high amount of rigidity for the gear and motor housing simultaneously.
Each drive is produced and tested particularly for each order and customer. A advanced modular system permits a great diversity of types and a optimum degree of customization to client requirements.
In both rotation directions, described end positions are protected by two position limit switches. This uncomplicated solution does not just simplify the cabling, but also makes it possible to configure the end positions quickly and easily. The high shut-off accuracy of the limit switches ensures safe operation shifting forwards and backwards.
A gearmotor provides high torque at low horsepower or low quickness. The speed specifications for these motors are normal speed and stall-acceleration torque. These motors make use of gears, typically assembled as a gearbox, to reduce speed, making more torque obtainable. Gearmotors ‘re normally utilized in applications that need a whole lot of force to move heavy objects.
More often than not, most industrial gearmotors make use of ac motors, typically fixed-speed motors. Nevertheless, dc motors can also be used as gearmotors … a whole lot of which are found in automotive applications.
Gearmotors have several advantages over other types of motor/equipment combinations. Perhaps most importantly, can simplify style and implementation by eliminating the stage of separately creating and integrating the motors with the gears, thus reducing engineering costs.
Center-drive gear motor Another advantage of gearmotors is definitely that having the right combination of engine and gearing can prolong design life and allow for optimum power management and use.
Such problems are common when a separate electric motor and gear reducer are connected together and lead to more engineering time and cost along with the potential for misalignment leading to bearing failure and eventually reduced useful life.
Improvements in gearmotor technology include the use of new specialty materials, coatings and bearings, and also improved gear tooth styles that are optimized for noise reduction, increase in power and improved life, which allows for improved performance in smaller deals. More after the jump.
Conceptually, motors and gearboxes could be combined and matched as needed to best fit the application form, but in the end, the complete gearmotor is the driving factor. There are a variety of motors and gearbox types that can be mixed; for example, the right position wormgear, planetary and parallel shaft gearbox could be combined with permanent magnet dc, ac induction, or brushless dc motors.
