For applications where variable speeds are essential, typically an AC engine with an Inverter or brush motors are used. Brushless DC motors are a sophisticated option because of their wide quickness range, low heat and maintenance-free operation. Stepper Motors offer high torque and even low speed operation.
Speed is typically managed by manual operation on the driver or by an external switch, or with an exterior 0~10 VDC. Speed control systems typically use gearheads to increase result torque. Gear types range from spur, worm or helical / hypoid depending on torque needs and budgets.
Mounting configurations vary to based on space constraints or style of the application.
The drives are powerful 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 application of aluminium die casting technology, which ensures a high amount of rigidity for the gear and motor housing at the same time.
Each drive is produced and tested specifically for each order and customer. A advanced modular system allows for an excellent 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 remedy does not just simplify the cabling, but also makes it possible to configure the end positions efficiently. The high shut-off accuracy of the limit switches guarantees safe operation shifting forwards and backwards.
A gearmotor delivers high torque at low horsepower or low acceleration. The speed specifications for these motors are normal speed and stall-quickness torque. These motors use gears, typically assembled as a gearbox, to lessen speed, making more torque offered. Gearmotors ‘re normally used in applications that require a lot of force to go heavy objects.
By and large, most industrial gearmotors use ac motors, typically fixed-speed motors. Nevertheless, dc motors may also be used as gearmotors … a lot of which are used in automotive applications.
Gearmotors have a number of advantages over other styles of motor/equipment combinations. Perhaps most of all, can simplify design and implementation by eliminating the step of separately designing and integrating the motors with the gears, thus reducing engineering costs.
Another advantage of gearmotors can be that getting the right combination of engine and gearing may prolong design life and invite for maximum power management and use.
Such problems are common when a separate motor and gear reducer are linked together and lead to more engineering time and cost as well as the potential for misalignment leading to bearing failure and eventually reduced useful life.
irrigation gearbox Advances in gearmotor technology include the use of new specialty components, coatings and bearings, and in addition improved gear tooth designs that are optimized for noise 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 could be mixed and matched as had a need to best fit the application form, but in the finish, the complete gearmotor may be the driving factor. There are a number 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.
