A Parallel Shaft Brushless DC Motor is an integrated drive system that combines a brushless motor with a parallel-axis gearbox. Its input and output shafts remain parallel, resulting in linear power transmission. It utilizes electronic commutation instead of traditional brushes, combined with a precision helical gear reduction mechanism, to achieve high torque output in a compact size.
Transmission efficiency: Orthogonal shafts require a 90° change in power direction, resulting in energy loss; parallel shafts are linear drives with extremely low mechanical losses, achieving an efficiency of over 95%.
Cost advantage: Relatively simple structure, easier gear manufacturing, and more affordable compared to orthogonal shaft motors, making it the preferred choice for budget-sensitive projects.
Radial space: The Parallel Shaft Brushless DC Motor is suitable for scenarios with limited longitudinal space but ample lateral space (such as long, narrow assembly lines).
Ultra-high energy efficiency: Utilizing a precision helical or spiral gear design, it boasts high meshing and a transmission efficiency generally exceeding 95%. Compared to right-axis motors, it generates less heat and saves more energy over long-term operation, making it an ideal choice for energy-saving retrofits.
Exceptional cost-effectiveness: As the most mature reducer structure, its manufacturing and maintenance costs are lower than those of right-axis motors. While meeting space requirements, it can save you 20%-30% on hardware procurement costs.
Vertically compact: Although its lateral length is relatively long, its height (stack thickness) is extremely thin. It is ideal for installation in equipment with limited height but ample length space, such as precision labeling machines and thin-layer conveyor belts.
Smooth operation and maintenance-free: The brushless motor + enclosed gearbox structure not only has a lifespan of over 20,000 hours but also operates with extremely low noise. Unlike brushed motors, it eliminates the need for regular carbon brush replacements, truly achieving "one-time installation, long-term peace of mind."
Note: Parallel Shaft Brushless DC Motors occupy a large amount of space in the horizontal (length direction). If the internal space of the equipment is extremely narrow, please give priority to orthogonal axis or flat axis motors.
Industrial automated production lines: Conveyor belt drives, packaging machine spindles, labeling machine rollers, material hoists.
Commercial and food equipment: Commercial mixers, coffee grinders, vending machine dispensing mechanisms, rotary ovens.
Smart home and building applications: Electric roller shutters, smart clothes racks, residential ventilation systems.
Torque Margin: When selecting a motor, the actual load torque should be less than 70% of the rated torque to cope with the impact of frequent starts and stops and extend the motor's lifespan.
Space Allowance: Due to its linear structure, sufficient lateral length space must be reserved during installation, and a cooling duct must be ensured at the motor tail (fan end).
Reverse Connection Prevention: Reversing the positive and negative terminals of the power supply is strictly prohibited, otherwise the drive board will be instantly burned out.
Signal Differentiation: It is essential to distinguish between the three-phase power lines (UVW) and the Hall/encoder signal lines. Incorrect connection will cause the motor to vibrate or not rotate.
No Impact: When installing pulleys or couplings, Parallel Shaft Brushless DC Motor is strictly forbidden to strike the motor output shaft to avoid damaging the internal bearings and gears.
Cooling Management: Although highly efficient, it is recommended to install a cooling fan when operating continuously in high-temperature environments above 40℃ or in a closed enclosure.
Packaging Standard: The Parallel Shaft Brushless DC Motor body is wrapped in thickened EPE pearl cotton and placed in a high-strength five-layer corrugated cardboard box to effectively prevent squeezing and vibration during transportation.
Delivery Time: For standard models and non-standard customized models (such as special shaft lengths or voltages), please consult customer service.
Q1: Which is better, a Parallel Shaft Brushless DC Motor or a right-axis motor?
A: It depends on your equipment space. If there is ample lateral space and you prioritize high efficiency and low cost, a parallel-axis motor is the absolute first choice (efficiency > 95%). If the internal space of your equipment is limited and requires "bend-height" installation, then a right-axis motor must be chosen.
Q2: Does this type of motor require lubrication maintenance?
A: No. This product uses a fully enclosed grease lubrication structure (lifetime maintenance-free design). It is pre-lubricated with special grease at the factory, and users do not need to add lubricating oil during its normal service life.
Q3: Why is it said to be more energy-efficient than a right-axis motor?
A: Because the power transmission path is different. A right-axis motor needs to change direction by 90 degrees through bevel gears, resulting in greater friction loss (efficiency approximately 85%). A parallel-axis motor transmits power linearly, with extremely low mechanical loss, thus achieving higher energy conversion efficiency.
Q4: Is it normal for the motor to heat up?
A: In an ambient temperature below 40℃, a motor surface temperature reaching 60-70℃ is normal. However, if it becomes too hot to touch (above 90℃) or has a burnt smell, please stop the machine immediately and check it. This may be due to excessive load, single-phase operation, or poor heat dissipation.
Q5: Can it be used with a speed controller?
A: Absolutely. This motor comes standard with a dedicated driver that supports 0-10V analog input, PWM signal, or potentiometer speed regulation, enabling stepless smooth adjustment from 0 RPM to rated speed.
