## What is a gearbox DC motor?

What is a DC Gear Motor? A gear motor is an all-in-one combination of a motor and gearbox. The addition of a gear head to a motor reduces the speed while increasing the torque output. The most important parameters in regards to gear motors are speed (rpm), torque (lb-in) and efficiency (%).

### How do I choose a gearbox motor?

Sizing to the motor may be simpler and result in a gearbox that works, but it will result in the purchase of a larger gearbox than is needed….Basics of Gearbox Selection

- Service Factor.
- Ambient Temperature and Environment.
- Shock Load or Type of Load.
- Output Style or Mechanism.
- Output Shaft or Hollow Bore Size.

**What’s the difference between a gearbox and a motor?**

A gearbox—otherwise known as a gear reducer or speed reducer—is a set of gears that can be added to a motor to drastically decrease speed and/or increase torque. Groschopp offers four different types of gear reducers: Planetary, Parallel Shaft, Right Angle Worm and Right Angle Planetary (Bevel).

**How do I choose a DC gear motor?**

The three main specifications you will need to know for any DC motor application are voltage, speed and torque. Once these aspects are determined, you are now ready to get started on your journey to select the ideal motor solution. The key is to use a motor that is operating at or near its maximum efficiency.

## Why do we use gearbox in motor?

The purpose of a gearbox is to increase or reduce speed. As a result, torque output will be the inverse of the speed function. If the enclosed drive is a speed reducer (speed output is less than speed input), the torque output will increase; if the drive increases speed, the torque output will decrease.

### How do you calculate the power of a gearbox?

Motor power = torque ÷ 9550 × Rated power’s motor input speed /Ratio /service factor. [1] Service factor(f.s.):…How to calculate gearbox output torque?( gearbox output torque calculation formula)

Code | Description | Unit |
---|---|---|

T2 | Gearbox output torque | N.m (Kgs.m) |

P1 | Input Power | Kw |

n1 | Input speed | r/min (RPM) |

i | Total ratio | – |

**Which gear gives the most power?**

First gear provides the most pulling power but the least potential for speed, whilst fifth gear which provides the least pulling power allows the greatest range of speed.

**What happens if you run a 12v motor on 24v?**

If you run a 12v motor from 24v its current drain and speed will still depend on the mechanical loading. However under no load it will now run at twice the speed at which it originally ran with 12v. Heating in the motor is still related to the current – so you can still run it at its full rated mechanical load/current.

## What happens when you run a 24 volt motor on 12 volts?

24v hooked to 12v will spin for a while on a full battery but there will be no torque. You could stop it with your hand. It is like running your motor with half the spark plugs missing.

### What is difference between gearbox and gear motor?

Simply put, a gear motor is an electric motor coupled with a gearbox. In most cases, the addition of a gearbox is intended to limit the speed of the motor’s shaft and increase the motor’s output torque.
