For applications where adjustable speeds are essential, typically an AC motor with an Inverter or brush motors are used. Brushless DC motors are a sophisticated option due to their wide quickness range, low heat and maintenance-free procedure. Stepper Motors provide high torque and smooth 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 Center-drive gear motor drives are powerful and durable and show a compact and lightweight design.
The compact design is manufactured possible through the mixture of a spur/worm gear drive with motors optimized for performance. This is achieved through the constant application of aluminium die casting technology, which ensures a high amount of rigidity for the apparatus and motor housing at the same time.
Each drive is produced and tested specifically for every order and customer. A advanced modular system allows for a great diversity of types and a optimum degree of customization to client requirements.
In both rotation directions, described end positions are guarded by two position limit switches. This uncomplicated alternative does not only 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 shifting forwards and backwards.
A gearmotor provides high torque at low horsepower or low velocity. The speed specs for these motors are normal speed and stall-velocity torque. These motors use gears, typically assembled as a gearbox, to reduce speed, making more torque offered. Gearmotors are most often used in applications that need a whole lot of force to move 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 used in automotive applications.
Gearmotors have several advantages over other styles of motor/gear combinations. Perhaps most of all, can simplify design and implementation through the elimination of the step of separately developing and integrating the motors with the gears, thus reducing engineering costs.
Another benefit of gearmotors is that getting the right combination of engine and gearing may prolong design life and allow for the best possible power management and use.
Such problems are common when a separate electric motor and gear reducer are linked 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 use of new specialty components, coatings and bearings, and in addition improved gear tooth designs that are optimized for sound reduction, increase in power and improved life, all of which allows for improved overall performance in smaller deals. More after the jump.
Conceptually, motors and gearboxes can be blended and matched as needed to greatest fit the application, but in the finish, the complete gearmotor may be the driving factor. There are numerous of motors and gearbox types which can be mixed; for example, the right position wormgear, planetary and parallel shaft gearbox can be combined with long lasting magnet dc, ac induction, or brushless dc motors.
