Custom Brushless DC (BLDC) Motor Solutions

BEI Kimco specializes in customizing brushless DC motors to exact customer specifications, giving them the ideal solution for their needs. Utilizing decades of experience and proprietary magnetic design software, these custom motors are designed with the customers budget in mind and optimized for use in their application. If you are interested in a custom motor, or would like to know more about our capabilities, please contact us.


Frameless BLDC Motor (Rotor/Stator Part Set) Options:

Frameless Inner & Outer Rotational Member Configurations:
Both inner and outer rotating member design options can be used to support the integration of the components within our customer’s next higher assembly. While the inside rotor design may offer superior acceleration characteristics, the higher inertial outside rotation design generally provides better rotational stability and mounting flexibility.
Sine and Trapezoidal BEMF Drive Winding Configurations:
Both sine and trapezoidal based BEMF winding configuration options can be used to accommodate our customer’s commutation and control schemes to achieve optimum operating efficiencies. These options can be supported with Hall commutated and sensor-less controls.
Magnetic Design Optimization for Constant Velocity and Position Based Motion Profiles:
BEI Kimco’s advanced magnetics design capability allows for effective optimization of motor torque and mechanical performance based on decades of experience and proprietary design methodologies. Custom laminations, winding configurations and magnetic pole shaping options support cost efficient design solutions with minimal up-front tooling investment.


Housed BLDC Motor Options:

Custom Shaft and Mounting Options:
A wide range of custom single and dual shaft configurations, as well as mounting options are available to facilitate a brake, external resolvers, encoders, gear reducers and other devices.
Anti-vibration and Noise Reduction Features:
Various noise reduction and anti-vibration design techniques are employed to achieve optimal acoustic noise performance. These include the use of proprietary magnetic circuit and mechanical component design methodologies which include magnet and skewed stack configuration.
Bearing Options:
A wide variety of high quality (ABEC 5 or better) open, shielded and sealed bearing options are available. Each selected option can be complimented with custom grease selections and fill levels to support minimum running current and resistance to external environmental factors. Customer bearing selections are most often dictated by product reliability, mechanical robustness and acoustical noise performance requirements.
Sine and Trapezoidal BEMF Drive Winding Configurations:
Both sine and trapezoidal based BEMF winding configuration options can be used to accommodate our customer’s commutation and control schemes to achieve optimum operating efficiencies. These options can be supported with Hall commutated and sensor-less controls.


High Pressure High Temperature (HPHT) Housed & Frameless BLDC Motor Options:

A variety of options are available to complement the severe environment downhole (MWD/LWD) application product offerings. These BLDC motors can be supplied with a variety of mounting hole, shaft and interface provisions that are compatible with many gear reduction and position feedback devices currently available on the market. BEI Kimco’s HPHT products offer a proprietary optional Hall Commutation option that has been qualified for 205 °C operation at pressures of up to 30K PSI. For more information, please click here. .
