“Gear motor” refers
to a combination of a motor plus a reduction geartrain
. These are often conveniently packaged together in one unit. … For large N, often the maximum output torque is limited by the strength of the final gears, rather than by N times the motor’s torque.
What is the gear motor?
Essentially, a gearmotor is
a pairing of gear reducer and ac or dc electrical motor
. The gear and the motors are combined into one unit. A gearmotor delivers high torque at low horsepower or low speed. … These motors use gears, typically assembled as a gearbox, to reduce speed, which makes more torque available.
What is the function of gear motor?
A geared motor is a component whose
mechanism adjusts the speed of the motor, leading them to operate at a certain speed
. geared motor have the ability to deliver high torque at low speeds, as the gearhead functions as a torque multiplier and can allow small motors to generate higher speeds.
What are the main advantages of gear motors?
- High Torque Output.
- Speed Reduction.
- High Resolution.
- Drive Large Inertial Loads.
- Shorter Positioning Time.
- Downsize.
- Improved Damping Characteristics.
- Increased Axial and Radial Load.
What is the difference between motor and gear motor?
1 Answer. A DC motor is not the same as a “gear motor” – a “gear motor” may be an AC or DC motor coupled with a gearbox or transmission. A gear motor adds mechanical
gears to alter the speed/torque of the motor
for an application. Usually such an addition is to reduce speed and increase torque.
What are the 4 types of gears?
- Spur Gear. Spur gears transmit power through shafts that are parallel. …
- Helical Gear. Helical gears have teeth that are oriented at an angle to the shaft, unlike spur gears which are parallel. …
- Double Helical Gear. …
- Herringbone Gear. …
- Bevel Gear. …
- Worm Gear. …
- Hypoid Gear.
What is the working principle of gear motor?
A gearbox uses
mechanical advantage to increase output torque and reduce RPM
. The motor’s shaft is feed into the gearbox and through a series of internal gearing provides the torque and speed conversion. Our gearboxes are available in a variety of sizes and gear ratios to meet a wide range of torque requirements.
What is the principle of gear?
Gears use the principle of
mechanical advantage
, which is the ratio of output force to input force in a system. For gears, the mechanical advantage is given by the gear ratio, which is the ratio of the final gear’s speed to the initial gear’s speed in a gear train.
What is a gear DC motor?
A geared DC Motor
has a gear assembly attached to the motor
. … Using the correct combination of gears in a gear motor, its speed can be reduced to any desirable figure. This concept where gears reduce the speed of the vehicle but increase its torque is known as gear reduction.
What is law of gearing?
Law of gearing states that
the common normal at the point of contact between a pair of teeth must always pass through the pitch point for all positions of mating gear
. … This is a must condition for the two gears to perform properly.
What is the price of gear motor?
| Phase Min Price Max Price | Single Phase Rs 1450/Piece Rs 20000/Piece | Three Phase Rs 1000/Piece Rs 26000/Piece |

Why are gears used with DC motors?
Gears Harness the Power of DC Motors
To reduce shaft speeds
, many DC motors are paired with a gearbox. This helps to reduce the motor’s shaft speed, and increase the torque output of the motor. In most cases, torque is increased by the ratio of the gear reduction, minus any losses in the gearbox.
What is the difference between a DC motor and gear motor?
A geared DC Motor has a gear assembly attached to the motor. … Using the correct combination of gears in a gear motor, its speed can
be reduced to
any desirable figure. This concept where gears reduce the speed of the vehicle but increase its torque is known as gear reduction.
What is inside a DC motor?
DC motors include two key components:
a stator and an armature
. The stator is the stationary part of a motor, while the armature rotates. In a DC motor, the stator provides a rotating magnetic field that drives the armature to rotate.
How do I choose a DC gear motor?
- Determine application requirements, see “Application Checklist”
- Select Motor Type, see “Motors Quick Reference Guide”
- Select matching speed and torque output for gear motor, see “Gear Motor Performance Curve”
Which gear goes the fastest?
Remember each car will be geared slightly differently, but a good rule of thumb for changing gears is that
first gear
is for speeds up to 10 mph, second gear is for speeds up to 15 mph, third gear is for speeds up to 35 mph, fourth gear is for speeds up to 55 mph, fifth gear is for speeds up to 65 mph, and sixth gear …
