The Schneider Electric BCH2MM2023CA6C is a high-performance Brushless AC Servo Motor belonging to the Lexium 28 series, specifically the BCH2 motor line. Designed for compact and high-dynamic motion control applications, this motor delivers a powerful combination of speed, torque, and precision in a standardized 130mm flange form factor. It is engineered to work seamlessly with Schneider’s Lexium 28 servo drives, forming an optimized servo bundle that is cost-effective, energy-efficient, and embedded with safety features.
This model is characterized by its 2000W (2 kW) power rating, 3000 RPM maximum speed, and a 22mm keyed shaft with an oil seal for harsh environments. It features a high-resolution absolute encoder and natural convection cooling, making it ideal for a wide variety of industrial machinery requiring precise positioning and smooth operation.

Key Features & Benefits
High Dynamic Performance:
- Optimized Inertia: Designed with a rotor inertia of 13.5 kg.cm², providing an excellent balance between acceleration capability and load matching for general automation tasks.
- High Speed: Capable of reaching a maximum mechanical speed of 3000 RPM, allowing for rapid cycle times in packaging, assembly, and material handling.
- Precision Control: Equipped with a 20-bit absolute encoder, ensuring precise position feedback even after power loss, eliminating the need for homing routines.
Robust Construction & Environmental Protection:
- IP65/IP50 Rating: The motor offers IP65 protection (dust-tight and protected against water jets) when mounted correctly (IM B5 or IM V1), making it suitable for washdown environments, food processing, and outdoor applications. IP50 is standard for other mountings (IM V3).
- Oil Seal: Includes an integrated oil seal on the shaft to prevent lubricant leakage and ingress of contaminants, extending motor life in dirty or oily environments.
- Natural Convection Cooling: The 130mm frame utilizes natural air convection, eliminating the need for cooling fans, reducing noise, and minimizing maintenance.
Seamless Integration & Connectivity:
- MIL Connector: Comes standard with a MIL (D-Sub) connector for power and feedback, providing a robust and industry-standard connection that resists vibration.
- Plug-and-Play with Lexium 28: Pre-configured parameters allow for instant recognition and auto-tuning when connected to Lexium 28 series drives, significantly reducing commissioning time.
- Safety Integrated: Supports safe torque off (STO) and other safety functions via the connected drive, meeting SIL 3 / PL e safety standards.
Compact & Efficient Design:
- Space-Saving: The 130mm flange is significantly more compact than traditional 180mm motors for the same power class, saving valuable cabinet space.
- Energy Efficiency: High-efficiency motor design reduces heat generation and power consumption, contributing to lower operational costs.
