For applications where adjustable speeds are essential, typically an AC electric motor with an Inverter or brush motors are used. Brushless DC motors are an advanced option due to their wide acceleration range, low temperature and maintenance-free procedure. Stepper Motors provide high torque and clean low speed operation.
Speed is typically managed by manual operation on the driver or by an external change, or with an exterior 0~10 VDC. Rate control systems typically utilize gearheads to increase output torque. Gear types range from spur, worm or helical / hypoid depending 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 show a concise and lightweight design.
The compact design is made possible through the combination of a spur/worm gear drive with motors optimized for performance. This is achieved through the constant application of light weight aluminum die casting technology, which ensures a high Center-drive gear motor degree of rigidity for the gear and motor housing simultaneously.
Each drive is produced and tested particularly for each order and customer. A sophisticated modular system allows for an excellent diversity of types and a maximum degree of customization to customer requirements.
In both rotation directions, described end positions are guarded by two position limit switches. This uncomplicated option does not just simplify the cabling, but also makes it possible to configure the finish positions quickly and easily. The high shut-off precision of the limit switches guarantees safe operation shifting forwards and backwards.
A gearmotor delivers high torque at low horsepower or low velocity. The speed specifications for these motors are regular speed and stall-rate 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 lot of force to go heavy objects.

More often than not, most industrial gearmotors make use of ac motors, typically fixed-speed motors. Nevertheless, dc motors may also be utilized as gearmotors … a lot of which are found in automotive applications.
Gearmotors have several advantages over other types of motor/gear combinations. Perhaps most of all, can simplify design and implementation by eliminating the stage of separately designing and integrating the motors with the gears, hence reducing engineering costs.
Another benefit of gearmotors can be that getting the right combination of electric motor and gearing may prolong design life and invite for maximum power management and use.

Such problems are normal when a separate motor and gear reducer are connected together and result in more engineering time and cost as well as the potential for misalignment leading to bearing failure and eventually reduced useful life.
Developments in gearmotor technology include the utilization of new specialty materials, coatings and bearings, and also improved gear tooth styles that are optimized for noise reduction, increase in strength and improved life, all of which allows for improved efficiency in smaller packages. More after the jump.
Conceptually, motors and gearboxes can be blended and matched as needed to greatest fit the application form, but in the end, the complete gearmotor may be the driving factor. There are a variety of motors and gearbox types which can be combined; for example, the right angle wormgear, planetary and parallel shaft gearbox can be combined with permanent magnet dc, ac induction, or brushless dc motors.
