What is Nord Gear Motor and what are the advantages of Nord Geared Motor

1. Nord Gearmotors are a great illustration of an integrated system in the manufacturing and industrial
sphere which provides high levels of energy efficiency without compromising the effectiveness of the
process. Typically, a gearmotor is simply a single unit that amalgamates a gear reducer with an electric
motor, assembled inside a gearbox, and so providing high torque at a low horsepower.
AC motors are normally used in gearmotor units mainly because of their variable-speed specification
which has its advantages particularly in when a variable speed motor is preferable; however, DC motors
can be used in a gearmotor unit for functions that demand constant speed motors. In this article are a
few of the primary features that make the gearmotor unit more popular than other combinations of
gear-motor.
1. Torque multiplication
Nord gearmotors couple gears to a motor output shaft so that heavy objects can easily be lifted thanks
to the increased torque. This happens due to the gears being fixed in the correct gear ratio hence
achieving a mechanical advantage which produces an output torque depending on the efficiency of the
gearhead. Moreover, this powerful device has the capacity to withstand, as well as transmit, more
torque in a uniform and consistent manner.
2. Speed reduction
The Nord Gear Motor works as a speed reducer, due to the fact that it increases the output torque
whilst at the same time decreasing the output speed. This is chiefly due to the fact that the gearbox
ratio decreases the rpm of the motor while it in turn improves the performance of the system, in
combination with supplying the torque needed by a machine in order to properly function.
3. Durability
Gear motors are a single unit comprising a number of sub-systems which are built by the manufacturer
to work mutually. Consequently there are minimal chances of parts being misaligned, as can transpire if
you separately design and assimilate the motors and gears by yourself. This means that, the gearmotor
is inclined to operate effectively for an extended period, without any mechanical problems hence giving
you great service for a longer period. Having a gearbox moreover, reduces the threat of overheating
which might otherwise reduce the robustness of the gearmotor.
4. Inertia Matching
Dense copper windings and high energy magnets are the normal characteristics of servomotors; and
though this may be efficient it could trigger inertia mismatches between the servomotors and the loads
that they manage. Where there is an inertia mismatch, the system will experience an increase in settling
time and excessive overshoot both of which reduces the production line throughput. On the other hand,
Nord gearmotors assures a match between the motor and load inertia because of the gearhead that
offsets the balance between both inertia forces, which results in a unit that's far more responsive.

2. Having said that, choosing the correct gearmotor for any particular application isn't always that clear-
cut. Well, whilst picking out an individual gearmotor might seem like a “one-type fits all” situation, you
can take some procedural steps in order to make sure you go with a gearmotor that corresponds with
your required mechanical tasks. Listed here are simple select the best gearmotor for you;
1. Know your application requirements
Before choosing any geared motor, you should first have a look at the precise requirements of your
application in order to be sure they concur with the gearmotor specifications. These prerequisites
involve the gearmotor horsepower, the orientation of the mounting, and the required torque for the job
in hand. What's more, bearing in mind several other specifics like the input power source, acceptable
noise levels, the degree of maintenance, and weight may also help you to cast some light on what kind
of gearmotor to go for.
You need to also take note that gear subtypes affect applications in diverse ways.. As an illustration spur
gears have a high gear ratio and are cost effective however are noisy mainly due to the fact that their
teeth are positioned perpendicular to the gear face which additionally makes them prone to wear and
tear. Worm gears in contrast to this aren't so noisy, can be used by different configurations, for instance
hollow-shaft and double shaft output and have a high. Nevertheless, worm gears are non-reversible and
have low efficiency.
Planetary gears function via a sun gear in the center which drives the surrounding gears. When
planetary gears are employed in gearmotors they are known to have a compact size, work in a quiet
manner, and induce a high rate of torque. They are also very flexible because of the gears being
cylindrically shaped, which means it is feasible for the gearmotor to be utilized in diverse
implementations. Furthermore, owing to their better rolling and torsional stiffness, gearmotors units
using planetary gears promises great durability.
2. Know motor type
Using your prepared list of application requirements, compare them to the specifications of each
gearmotor. You must however keep in mind that different applications have particular requirements
and characteristics, thus it's vital that you pay most attention to the primary aspects like horsepower
and performance. AC gearmotors are popular with many users mainly because they are cost-effective,
durable, and give more control of speed than the other alternatives.
When you've selected your perfect gearmotor, a good way to make sure it's capable of the job, is to get
it running in a normal operating environment. If you decide that you are unsatisfied because the system
overheats or is very noisy, please get in contact with the supplier for replacement or repair. However, so
as to be able to effectively troubleshoot a gearmotor unit, you may think about getting yourself familiar
with these everyday reasons behind issues with gearmotors and how to prevent them;

3. • Excessive overhung loads
Excessive overhung loading not only damages the bearing support system but additionally the radial
load on the shaft, triggering shaft fatigue which can cause issues in loading and operating. To forestall
this, it is recommended to use limit switches or current sensors that cut the power in the event the
permitted load limit is surpassed.
• Inferior heat dissipation
Inferior dissipation of heat triggers gearmotor overheating which is chiefly a consequence of using Nord
gearmotors which are not big enough or operating them in an environment not suitable for them. It's
also vital to be aware that as well as ventilation holes being blocked, if the lubrication oil temperature of
the gearbox goes up sufficiently high, it will result in the overheating of the gearmotor causing it to fail.
