Inline Motor Gearbox
What is an Inline Motor Gearbox
An Inline Motor Gearbox is a power transmission device featuring an integrated design that combines an electric motor with a speed reducer. Since its input and output shafts are aligned along the same central axis, it is referred to as a "coaxial geared motor."
By utilizing an internal gear transmission system to reduce rotational speed and increase output torque, the device enables equipment to achieve stable and efficient power output at lower operating speeds. Due to its compact structure, ease of installation, and high transmission efficiency, coaxial geared motors are widely utilized in fields such as automation equipment, conveying machinery, packaging systems, warehousing and logistics, and industrial production lines.










Integrated Coaxial Structure, Compact Design: The motor and reducer are directly coupled coaxially, saving over 30% in installation space compared to parallel-shaft or right-angle shaft models.
High Torque and Load Capacity: Power output ranges from 0.12 to 160 kW, with torque reaching up to 26,000 Nm and robust overload resistance.
Flexible and Modular Installation: Supports both foot and flange mounting options; customizable speed ratios ranging from 3 to 1800; compatible with various motor types (standard, variable frequency, and brake motors).
Robust and Durable: Features a cast iron housing and alloy steel gears; dust-proof and leak-proof design ensures reliable performance in harsh operating environments.

Q1: Are coaxial motor reducers efficient?
A1: When utilizing helical or hardened-face gear structures, the overall transmission efficiency typically exceeds 95%.
Q2: Are coaxial motor reducers suitable for continuous operation?
A2: Yes, they are. High-quality coaxial geared motors are capable of meeting the demands of long-term continuous operation and are widely utilized in automated production lines.
Q3: How do I determine the appropriate reduction ratio for a coaxial geared motor?
A3: It is determined by calculating the ratio based on the required output speed of the equipment and the motor speed, while also taking into account the specific load characteristics during the selection process.
