For applications where variable speeds are necessary, typically an AC engine with an Inverter or brush motors are used. Brushless DC motors are a sophisticated option because of their wide velocity range, low warmth and maintenance-free operation. Stepper Motors provide high torque and smooth low speed operation.
Speed is typically managed by manual operation on the driver or by an exterior switch, or with an external 0~10 VDC. Acceleration control systems typically make use of gearheads to increase result torque. Gear types range from spur, worm or helical / hypoid depending on torque demands and budgets.
Mounting configurations vary to depending on space constraints or style of the application.
The drives are high performance and durable and feature 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 consistent application of light weight aluminum die casting technology, which guarantees a high degree of rigidity for the apparatus and motor housing concurrently.
Each drive is produced and tested specifically for every order and customer. A sophisticated modular system allows for a great diversity of types and a maximum degree of customization to customer requirements.
In both rotation directions, defined end positions are secured by two position limit switches. This uncomplicated alternative does not only simplify the cabling, but also can help you configure the finish positions quickly and easily. The high shut-off precision of the limit switches guarantees safe operation shifting forwards and backwards.
A gearmotor delivers high torque at low horsepower or low rate. The speed specifications for these motors are normal speed and stall-speed torque. These motors use gears, typically assembled as a gearbox, to reduce speed, making more torque obtainable. Gearmotors ‘re normally Center-drive gear motor utilized in applications that require a whole lot of force to move heavy objects.
More often than not, most industrial gearmotors make use of ac motors, typically fixed-speed motors. Nevertheless, dc motors can also be utilized as gearmotors … a whole lot of which are found 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 through the elimination of the step of separately designing and integrating the motors with the gears, hence reducing engineering costs.
Another benefit of gearmotors can be that having the right combination of engine and gearing can prolong design life and invite 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 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 designs that are optimized for sound reduction, increase in strength and improved life, all of which allows for improved performance in smaller packages. More after the jump.
Conceptually, motors and gearboxes can be mixed and matched as had a need to greatest fit the application, but in the finish, the complete gearmotor may be the driving factor. There are a variety 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.
