For applications where variable 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 swiftness range, low high temperature and maintenance-free procedure. Stepper Motors offer high torque and even low speed operation.
Speed is typically controlled by manual operation on the driver or by an exterior change, or with an exterior 0~10 VDC. Acceleration control systems typically make use of gearheads to increase output torque. Gear types range between spur, worm or helical / hypoid based on torque needs and budgets.
Mounting configurations vary to depending on space constraints or style of the application.
The drives are powerful and durable and feature 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 application of aluminum die casting technology, which guarantees a high amount of rigidity for the apparatus and motor housing simultaneously.
Each drive is produced and tested specifically for every 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, defined end positions are protected by two position limit switches. This uncomplicated answer 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 ensures safe operation moving 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-quickness torque. These motors make use of gears, typically assembled as a gearbox, to reduce speed, which makes more torque available. Gearmotors ‘re normally used in applications that need a lot of force to move heavy objects.

More often than not, most industrial gearmotors make use of ac motors, typically fixed-speed motors. However, dc motors may also be used as gearmotors … a whole lot of which are found in automotive applications.
Gearmotors have numerous 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, therefore reducing engineering costs.
Another advantage of gearmotors can be that getting the right combination of electric motor and gearing can prolong design life and invite for the best possible power management and use.

Such irrigation gearbox problems are common when a separate motor and gear reducer are linked together and lead to more engineering time and cost along with the potential for misalignment causing bearing failure and ultimately reduced useful life.
Advances in gearmotor technology include the usage of new specialty materials, coatings and bearings, and in addition improved gear tooth designs that are optimized for noise reduction, increase in strength and improved life, all of which allows for improved functionality in smaller packages. More after the jump.
Conceptually, motors and gearboxes can be mixed and matched as needed to best fit the application form, but in the finish, the complete gearmotor is the driving factor. There are a number of motors and gearbox types that can be combined; for example, a right angle wormgear, planetary and parallel shaft gearbox could be combined with permanent magnet dc, ac induction, or brushless dc motors.
