Discover how direct drives revolutionize sound quality and why ATEK is the ideal solution.
What are the main advantages of a direct drive motor for high-precision turntables?
Direct drive motors offer a direct power transmission to the turntable, resulting in excellent speed stability (flutter fluctuations often below 0.025 % W.R.M.S.), fast start-stop times (e.g. 0.7 seconds to 33 1/3 RPM) and minimal vibrations . This results in precise and faithful audio reproduction.
How does a coreless motor design improve the performance of turntables?
Coreless direct drive motors eliminate the so-called ‘cogging’ (cogging torque), as they do not have iron cores in the stator. This leads to a particularly smooth rotation without torque pulsations, which is crucial for a distortion-free sound reproduction .
What is meant by ‘cogging’ and why is its elimination important in high-end audio?
‘Cogging’ or cogging torque refers to small, unwanted torque fluctuations in motors with iron cores. In turntables, this can lead to audible flutter fluctuations. Elimination through coreless designs is important for maximum sound fidelity and precision..
Can ATEK develop custom direct drive motors for specific turntable designs?
Yes, ATEK Drive Solutions specializes as a system provider in the development of custom drive solutions. We can develop direct drive motors that are precisely tailored to individual requirements concerning dimensions, torque, control integration and other performance parameters for high-precision turntables.
What performance improvements can be expected from modern direct drive motors in speed stability?
Modern direct drive motors, especially with coreless technology and advanced control (e.g. Delta-Sigma-Drive), achieve outstanding flutter fluctuations often below 0.025 % W.R.M.S. This represents a significant improvement over older designs and is key for high-precision audio reproduction.
What factors, besides the motor, are crucial for the optimal sound quality of a direct drive turntable system?
For optimal sound quality, the entire system is crucial. This includes, in addition to a precise motor, also a high-quality tonearm, a suitable cartridge, a vibration-damping platter and a stable, resonance-optimized chassis. ATEK considers this system concept in development.
How does the development of motors for audiophile applications benefit from ATEK’s experience in industrial drive technology?
ATEK’s decades of experience in the industrial sector means expertise in precision manufacturing, reliability under demanding conditions, and system integration. These competencies are directly transferred into the development of high-performance and durable direct drive motors for audiophile applications, benefiting from minimal tolerances and high smoothness.
How maintenance-intensive is a high-quality direct drive motor typically?
High-quality direct drive motors are generally very low maintenance, as they do not have wear parts like rubber belts compared to belt drives. This ensures a consistently stable performance and reliability without regular replacement of drive components.
Direct drive motors, especially coreless designs , offer superior precision for turntables, which results in extremely low flutter fluctuations of under 0.025 % W.R.M.S. and thus in an unaltered sound reproduction .

Introduction: The magic of direct drive for perfect sound
Optimizing sound reproduction is central for audiophiles. Modern direct drive motors, especially a direct drive motor for high-precision turntables, significantly improve music reproduction. This article explains their technology and ATEK’s role in customized solutions.
What makes direct drives so special for audiophiles?
Direct drives couple the motor and platter directly, minimizing speed deviations and enabling excellent running stability. High-quality models achieve flutter fluctuations below 0.025 % W.R.M.S. Our servo motors offer similar precision.
The direct connection: Key to sound fidelity
Unlike belt drives with aging rubber belts, direct drives transfer power directly. This ensures a constant rotational speed and prevents disturbances caused by belt stretching or slipping. This consistency is essential for authentic sound reproduction, a quality characteristic that everyone direct drive motor for high-precision turntables strives for. DJ turntables achieve start times of 0.7s.
Advantages for DJs and demanding listeners
DJs appreciate direct drives for high torque and fast start-stop times. Audiophiles benefit from speed stability and low maintenance. A direct drive motor for high-precision turntables is a lasting solution for sound quality, supported by compact frameless motors.Technology depth: What makes direct drive motors superior
Coreless motor designs: The end of cogging
Modern coreless direct drive motors eliminate ‘cogging’ (cogging torque),a problem of earlier models, by omitting iron cores in the stator. This leads to smooth rotation without significant torque pulsations. Technics’ coreless motor in the SL-1200GAE set a standard in this respect.
Advanced motor control: Precision down to the detail
Highly developed motor controls with microcontrollers and algorithms (e.g. Delta-Sigma-Drive) ensure exact speed through continuous monitoring and correction. These systems also compensate for minor vibrations. The control of the Technics SL-1200GR is based on Blu-ray player technology.
Vibration minimization: The interplay between chassis and platter
Vibrations can significantly impact sound in sensitive turntables. Manufacturers utilize multilayer chassis and damped platters, to maximize performance, especially when using a direct drive motor for high-precision turntables is significant. The SL-1210GR platter (aluminum die-cast, 2.5 kg, vibration-absorbing rubber) is an example. Expertise in drive technology is crucial here.Benchmark analysis: The Technics SL-1200 series as a model
