For applications where variable speeds are necessary, typically an AC motor with an Inverter or brush motors are used. Brushless DC motors are a sophisticated option due to their wide speed range, low warmth and maintenance-free procedure. Stepper Motors provide high torque and clean low speed operation.
Speed is typically managed by manual operation on the driver or by an external change, or with an exterior 0~10 VDC. Rate control systems typically make use of gearheads to increase result torque. Gear types range from spur, worm or helical / hypoid based on torque needs 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 irrigation gearbox possible through the mixture of a spur/worm gear drive with motors optimized for performance. This is accomplished through the consistent application of aluminum die casting technology, which ensures a high amount of rigidity for the apparatus and motor housing concurrently.
Each drive is produced and tested particularly for every order and customer. A sophisticated modular system permits a great diversity of types and a maximum degree of customization to customer requirements.
In both rotation directions, defined end positions are shielded by two position limit switches. This uncomplicated solution does not only simplify the cabling, but also makes it possible to configure the end positions quickly and easily. The high shut-off precision of the limit switches guarantees safe operation shifting forwards and backwards.
A gearmotor provides high torque at low horsepower or low rate. The speed specifications for these motors are normal speed and stall-acceleration torque. These motors make use of 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 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 a number of advantages over other styles of motor/gear combinations. Perhaps most importantly, can simplify design and implementation by eliminating the stage of separately creating and integrating the motors with the gears, thus 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 optimum power management and use.
Such problems are common when a separate electric motor and gear reducer are connected together and lead to more engineering time and cost along with the potential for misalignment causing bearing failure and eventually reduced useful life.
Developments in gearmotor technology include the usage of new specialty components, coatings and bearings, and also improved gear tooth styles that are optimized for noise reduction, increase in power and improved life, which allows for improved efficiency in smaller packages. More following the jump.
Conceptually, motors and gearboxes could be blended and matched as had a need to best fit the application, but in the end, the complete gearmotor is the driving factor. There are numerous of motors and gearbox types which can be combined; for example, a right position wormgear, planetary and parallel shaft gearbox can be combined with permanent magnet dc, ac induction, or brushless dc motors.
