For applications where variable 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 operation. Stepper Motors offer high torque and smooth low speed operation.
Speed is typically controlled by manual operation on the driver or by an exterior switch, or with an external 0~10 VDC. Rate control systems typically utilize gearheads to increase output torque. Gear types range from 
spur, worm or helical / hypoid based on torque demands and budgets.
Mounting configurations differ to based on space constraints or design of the application.
The drives are high performance and durable and show a compact and lightweight design.
The compact design is made possible through the combination of a spur/worm gear drive with motors optimized for performance. That is achieved through the consistent irrigation gearbox application of aluminum die casting technology, which guarantees a high amount of rigidity for the apparatus and motor housing at the same time.
Each drive is produced and tested particularly for every order and customer. A sophisticated modular system permits a great diversity of types and a optimum degree of customization to customer requirements.
In both rotation directions, defined end positions are safeguarded by two position limit switches. This uncomplicated remedy does not just simplify the cabling, but also can help you configure the finish positions efficiently. The high shut-off precision of the limit switches guarantees safe operation moving forwards and backwards.
A gearmotor delivers high torque at low horsepower or low swiftness. The speed specs for these motors are regular speed and stall-rate torque. These motors use gears, typically assembled as a gearbox, to lessen speed, making more torque obtainable. Gearmotors ‘re normally used in applications that need a lot of force to go heavy objects.
By and large, most industrial gearmotors make use of ac motors, typically fixed-speed motors. However, dc motors can also be used as gearmotors … a whole lot of which are found in automotive applications.
Gearmotors have several advantages over other styles of motor/gear combinations. Perhaps most importantly, can simplify design and implementation by eliminating the stage of separately creating and integrating the motors with the gears, thus reducing engineering costs.
Another advantage of gearmotors can be that having the right combination of electric motor and gearing may prolong design life and invite for ideal power management and use.
Such problems are normal when a separate electric motor and gear reducer are linked together and lead to more engineering time and cost as well as the potential for misalignment causing bearing failure and eventually reduced useful life.
Developments in gearmotor technology include the usage of new specialty materials, coatings and bearings, and in addition improved gear tooth styles that are optimized for noise reduction, increase in power and improved life, which allows for improved efficiency in smaller deals. More after the jump.
Conceptually, motors and gearboxes can be combined and matched as had a need to greatest fit the application form, but in the end, the complete gearmotor may be the driving factor. There are a number of motors and gearbox types that can be mixed; for example, the right angle wormgear, planetary and parallel shaft gearbox can be combined with permanent magnet dc, ac induction, or brushless dc motors.
