An inline helical geared motor combines an electric motor and a helical gearbox in one compact unit, with the output shaft aligned with the motor shaft. It is one of the most common industrial drives because it offers efficient power transmission, smooth operation and straightforward installation.
For industrial buyers searching for Nord geared motor dealers in Tarapur MIDC, Boisar and surrounding industrial areas, understanding the selection process helps ensure the right drive for each application. This guide explains how to choose an inline helical geared motor, with a practical calculation example for process industries.
Inside the gearbox, helical gears with angled teeth transmit power from the motor to the output shaft. Their gradual engagement generally provides smoother and quieter operation than straight-cut gears and supports substantial load transmission.
Because the input and output shafts are aligned, an inline helical geared motor provides a compact drive arrangement. It suits machines that do not require a right-angle output.
Nord Drivesystems offers inline helical gearboxes and geared motors, and Dynamic Products supplies these products as a channel partner.
Businesses looking for a Nord Inline Helical Gearbox distributor can enquire about suitable gearbox configurations for conveyors, mixers, packaging machinery and other industrial applications.
An experienced Nord Inline Helical Gearbox dealer can help evaluate the required gear ratio, output torque, mounting arrangement and operating conditions before recommending a suitable solution.
Inline helical geared motors are used across a range of industrial applications, including:
For applications requiring different shaft arrangements, industrial buyers can also consult a Nord Parallel Shaft Geared Motor dealer to explore suitable drive configurations for conveyors, production lines and material handling equipment.
Step 1: Define the output speed and gear ratio.
Calculate the gear ratio by dividing the motor speed by the required output speed.
Gear ratio = Motor speed ÷ Required output speed
For example, a four-pole motor running at approximately 1,440 rpm with a required output speed of 60 rpm needs a ratio of:
1,440 ÷ 60 = 24:1
Step 2: Calculate the required torque.
Use the following formula:
Torque (Nm) = 9,550 × Power (kW) ÷ Speed (rpm)
For example, a 5.5 kW motor operating at an output speed of 60 rpm gives:
9,550 × 5.5 ÷ 60 ≈ 875 Nm
This is an ideal calculation. Actual output torque depends on gearbox efficiency and operating conditions. Always verify the manufacturer’s rated output torque.
Step 3: Apply the service factor.
The service factor accounts for the actual operating conditions of the machine. Smooth, uniform loads may require a lower service factor than applications involving frequent starts, shock loads or heavy-duty operation.
Multiply the calculated torque requirement by the applicable service factor, then select a gearbox that meets the resulting requirement. Use the manufacturer’s selection tables to confirm the correct rating.
Step 4: Choose the mounting and shaft type.
Determine whether the application requires foot mounting or flange mounting, a solid shaft or hollow shaft, and horizontal or vertical installation.
Vertical mounting and heavy radial or axial loads on the output shaft require particular attention during selection.
Step 5: Match the operating environment.
Chemical plants and humid coastal industrial locations such as Tarapur MIDC may require corrosion-protective coatings, suitable seals and an appropriate ingress protection (IP) rating.
For classified hazardous areas, check whether an appropriately certified explosion-protected motor is required.
Step 6: Confirm the motor specifications.
Verify the supply voltage, frequency, motor efficiency class, brake requirements and compatibility with a variable frequency drive (VFD).
For assistance with these requirements, a Nord Helical Geared Motor supplier can help you enquire about available drive options and their suitability for your application.
Avoid these common mistakes when selecting an industrial geared motor:
An inline helical gearbox is suitable when the application requires aligned input and output shafts. However, alternative gearbox arrangements may be more appropriate for specific machinery.
If your machine requires the output shaft at 90 degrees to the motor, a bevel helical gearbox may be a suitable option. For such applications, consult a Nord Bevel Helical Gearbox supplier to enquire about available configurations and application requirements.
For applications requiring speed reduction with different torque and mounting characteristics, a Nord Helical Speed Reducers supplier can help you explore suitable speed reducer options.
Planetary gearboxes may also be worth considering where high torque and compact dimensions are important. The final choice depends on the required torque, gear ratio, duty cycle, mounting arrangement and operating environment.
Selecting the right geared motor involves more than matching the motor power. Gear ratio, output torque, service factor, shaft configuration and environmental conditions all influence the final selection.

A geared motor combines an electric motor and gearbox into one assembly. A standalone gearbox requires a separate motor and an appropriate coupling or adapter.
Divide the motor speed in rpm by the required output speed in rpm. For example, 1,440 rpm divided by 60 rpm gives a ratio of 24:1.
A service factor is a multiplier used to account for operating conditions such as shock loads, daily operating hours and starts per hour. It helps ensure that the selected gearbox is appropriately rated for the application.
Many geared motor configurations can operate with a VFD, subject to motor compatibility, cooling requirements and the permitted speed range. Confirm the specifications with the manufacturer before installation.
Industrial buyers can contact Dynamic Products through the Nord product page to enquire about Nord geared motors, gearboxes and suitable drive configurations. Product availability and application suitability should be confirmed with the supplier.
A bevel helical gearbox is generally considered when the application requires a change in the direction of power transmission, such as a right-angle output. Selection depends on the machine layout, torque, speed and mounting requirements.
