For applications where variable speeds are essential, typically an AC motor with an Inverter or brush motors are used. Brushless DC motors are an advanced option because of their wide speed range, low warmth and maintenance-free operation. Stepper Motors provide high torque and simple low speed operation.
Speed is typically managed by manual operation on the driver or by an external change, or with an external 0~10 VDC. Acceleration control systems typically utilize gearheads to increase result torque. Gear types range from spur, worm or helical / hypoid depending 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 mixture of a spur/worm gear drive with motors optimized for performance. That is attained 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 particularly for each order and customer. A advanced modular system allows for a great diversity of types and a optimum amount of customization to consumer requirements.
In both rotation directions, defined end positions are guarded by two position limit switches. This uncomplicated answer does not only simplify the cabling, but also makes it possible to configure the end positions efficiently. The high shut-off accuracy of the limit switches ensures safe operation moving forwards and backwards.
A gearmotor provides high torque at low horsepower or low velocity. The speed specifications for these motors are normal speed and stall-speed torque. These motors make use of gears, typically assembled as a gearbox, to reduce speed, making more torque obtainable. Gearmotors are most often used in applications that require a lot of force to move heavy objects.
By and large, most industrial gearmotors make use of ac motors, typically fixed-speed motors. Nevertheless, dc motors can also be utilized as gearmotors … a lot of which are found in automotive applications.
Gearmotors have a number of advantages over other types of motor/equipment combinations. Perhaps most importantly, can simplify style and implementation through the elimination of the stage of separately developing and integrating the motors with the gears, thus irrigation gearbox reducing engineering costs.
Another advantage of gearmotors is certainly that having the right combination of electric motor and gearing can prolong design life and allow for the best possible power management and use.
Such problems are normal when a separate motor and gear reducer are connected together and lead to more engineering time and cost as well as the potential for misalignment causing bearing failure and eventually reduced useful life.
Improvements in gearmotor technology include the use of new specialty components, coatings and bearings, and in addition improved gear tooth styles 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 could be combined and matched as had a need to best fit the application form, but in the end, the complete gearmotor is the driving factor. There are many of motors and gearbox types that can be mixed; for example, the right angle wormgear, planetary and parallel shaft gearbox could be combined with long lasting magnet dc, ac induction, or brushless dc motors.
