Case Study: Customized Oven Motor for Turkey

Customer Requirements
A large Turkish catering equipment manufacturer required the development of a high-performance motor to drive commercial rotary grills (Döner Grill). The motor needed to withstand Turkey’s high-temperature, high-humidity kitchen environments while meeting demands for continuous operation (12–18 hours), low noise, and high energy efficiency.

Challenges Analysis

Extreme Environment Adaptation

Turkish commercial kitchens often exceed 50°C, with grease and steam easily infiltrating the motor.

Traditional motors suffer from insulation degradation due to heat and reduced heat dissipation caused by grease buildup.

High Load & Stability

Must drive vertical rotating meat columns (80–120kg, including metal frames) with a starting torque exceeding 30Nm.

Continuous operation requires motor temperature rise to stay within K-class insulation standards (≤185°C).

Localization Requirements

Compatibility with Turkey’s 220V/50Hz grid (±15% voltage fluctuation).

Compliance with Turkish TSE (Türk Standardları Enstitüsü) safety certification and EU CE standards.

Customized Solutions

Motor Design & Material Upgrades

Heat Resistance:

H-class insulation materials (silicone resin + mica) with embedded NTC temperature sensors for real-time winding monitoring.

AISI 304 stainless steel housing with IP55 protection to block grease ingress.

Power Optimization:

Custom low-speed (15–20 RPM), high-torque permanent magnet synchronous motor (PMSM) paired with a worm gear reducer, achieving 92% efficiency (vs. 85% for traditional induction motors).

Smart Control Module

Integrated variable-frequency drive (VFD) for soft start to prevent meat column wobbling.

Built-in Wi-Fi for smartphone app control (speed adjustment, real-time monitoring), aligning with Turkey’s digitalization trends in foodservice.

Localization Adaptations

Wide voltage design (180V–264V) for unstable power in remote areas.

Turkish-language interface and partnerships with local service providers to establish spare parts warehouses in Istanbul and Ankara, ensuring 48-hour repair response.

Results & Feedback

Customer’s annual procurement volume increased by 30%, with equipment failure rates dropping from 12% to <2%.

Motor noise reduced to <55 dB (from 68 dB), complying with Turkish noise regulations for dining venues.

Energy consumption lowered by 18%, saving approximately 1,500 TL (≈$80) per motor annually in electricity costs.
