Lastest company news about Sources of Motor Noise and Control Strategies: From Structural Design to Operational Optimization
Sources of Motor Noise and Control Strategies: From Structural Design to Operational Optimization

2025-11-25

Motor noise can affect much more than just the acoustic environment; they can also reveal design or manufacturer defects. Motor noise control is an important aspect of performance for noise-sensitive applications like medical equipment, household appliances, electric powered passenger vehicles, and sanitation vehicles. The expected common sources of noise from motors are: Electromagnetic noise: Is generated in small amounts when there are periodic changes in magnetic forces, and where variations in the air gap or imbalances in the magnetic fields are present; period tonal operations can produce whining sounds or vibrations. Mechanical noise: Typically emanates from bearing tolerances, or imbalance in the rotor, or during misalignments during assembly, often more prevalent in larger size motors or faster speed motors. Aerodynamic noise: Is a component of air cooled motors, the air stream is disrupted by fan blades. Electrical switching noise: Audible frequency noise can occur in brush motors, or in systems operating as an inverter, that switching can typically be high pitched tones or mixtures of audible frequencies. The methods we can apply to control the above noises are typically: Structural Design Optimisation: This may include but is not limited to different slot shape, slot fill-factor improvements, and balancing tooth combinations of the stator-rotor combinations, for the purpose of reducing higher harmonics of the electromagnetic forces. Machined and Balanced Rotor: Machining will allow for concentric rotors and minimizing bearing edge clearance tolerances will contribute to mechanical vibration, which may include testing through dynamic modelling. Low nuisance noise bearings and elastic mounts that minimize shock transmission and has smaller path lengths for noise transmission. PWM Modulation frequency tuning: when motors are equipped with inverter systems it may be possible to slip audible sized noise frequencies into the noise frequency ranges that are away from sensitivity ranges, away from human perception. In higher end applications, for example, when an electric passenger vehicle motor is not only to be imposed to a NVH (Noise, Vibration and Harshness) quality standard, the expectation from the customer is that the power train will operate below 60 dB since stationary and during the whole range of speeds during its performance cycle. Good quality and attention to detail will be required during the power train material selection, machining tolerances, and electronic control techniques for example. As a company we have a long history of low noise motor design for both industrial and commercial applications. We can respond to our customers in terms of specialized designs for silent operation that have acoustic specifications, to improving products quality to the end user without polluting their experience with unexpected noise annoyance.

Latest company case about Electric Fire Truck Motors Empowering the Green Transformation of Emergency Rescue
Electric Fire Truck Motors Empowering the Green Transformation of Emergency Rescue

2026-01-06

As the world advances with new types of energy technologies and public safety continues to increase within urban environments, how electric fire trucks change will continue to move forward as a key component of emergency response. Electric fire trucks use electric motors, which play a major role in the fire truck's ability to function properly and efficiently.   The electric motors used in fire trucks differ from those found in most electric vehicles. The motor must be capable of providing instant high-efficiency power for rapid acceleration in emergency situations — enabling the fire truck to get to the scene, faster than it would otherwise. The ability of the electric motor to provide sustained high-torque output provides additional stability and control to the fire truck, especially for those with higher payloads (firefighting personnel/equipment). Additionally, electric motors must be highly durable and stable to function in extremely hot, humid and smoky fire environments.   To meet these extended levels of demands placed upon them, manufacturers have, of late, begun utilizing permanent magnet synchronous motors (PMSM) and high-efficiency AC induction motors in the new models of electric fire trucks currently being created. The combination of a PMSM motor and an AC induction motor is becoming commonplace due to both the overall superior energy efficiency of the motor types when used in conjunction with intelligent control systems used in today’s electric fire truck models, as well as having the capability to produce instantaneous high-efficiency power and provide precise demand-control via the use of speed regulation and regenerative braking, thus extending the life of the motor while reducing maintenance costs. Furthermore, silent mode and less vibration (as compared to the conventional fire truck engines) would allow for greater safety and reliability of the electric fire trucks when operating in emergency environments. As nations continue to implement carbon-reduction initiatives and develop “green” emergency response strategies, it is anticipated by many industry experts that electric fire trucks will become more widely adopted throughout the world in the near future. The high-efficiency electric motor will be the driving factor behind the shift to electric fire trucks. In addition to the innovative technology being implemented into electric fire trucks, the electric fire truck manufacturers will continue to develop advanced technology in other areas, such as power density, thermal management, and intelligent monitoring systems that provide superior performance during emergency response operations. The evolution of electric fire truck motors represents a paradigm shift not only of new energy (electric powered) systems, but also of an important contribution to public safety and sustainability of development.
