Introducing the Sanken SAM265M Series 3-phase Intelligent Motor Driver

Ideal for Heat Pumps and Robotic Industrial Applications.

Intelligent power modules are fundamental in helping the world achieve net zero CO2 emission targets, as we transition from fossil fuels to electric power. Power modules are used in motor drives and power conversion systems, playing a critical role in the overall performance and efficiency of these systems.

High-performance motor drivers are essential components in increasingly vital technology such as heat pumps and robotics. In both cases, motor drivers ensure precise control of motor speed, direction and position, crucial for maintaining accuracy and efficiency in those applications.

Representing Sanken Electric, Profusion offers a broad selection of Sanken motor drivers for heat pumps and robotics, as well as many other industrial applications.

Introducing the Sanken SAM265M Series 3-phase Intelligent Motor Driver

The SAM265M Series of compact, intelligent 3-phase power modules are designed for brushless motor drives and power inverters. The modules include IGBTs, soft recovery power diodes, driver ICs, a bootstrap diode with limiting resistors, and a temperature detection thermistor in one small package.

High Power

The SAM265M50BS3 featured here includes IGBTs with breakdown voltage (V_ce) rated at 650V and output current (I_c) rated at 50A, capable of driving a 3.7kW 3-phase motor.

Less Space

Implemented in a space saving 30-pin package, the SAM256M series offers superior performance in applications where efficiency and precision is crucial. Utilizing DCB (Direct Copper Bonding) the SAM265M offers more than 20% reduction in space while maintaining high performance.

Less Electrical Noise

The specially developed high-speed soft recovery diodes are effective in suppressing switching noise, resulting in low electrical radiation. The smaller package’s power components are mounted close together, further reducing electrical radiation.

Accurate Temperature Detection for Improved Reliability

The SAM265Mxx Series includes a thermistor mounted internally, directly on the power chip substrate, offering very accurate temperature detection and the ability to quickly respond to sudden temperature changes. The thermistor is accurate to within 5ºC of the power switching devices and is monitored by the internal protection circuit, which operates at 10ºC below the power devices. This ensures high reliability and safe shutdown in case of faults or over-temperature operation.

High Efficiency and Less Waste

The SAM265M’s high efficiency, combined with intelligent features such as thermal shutdown, overcurrent protection and undervoltage lockout, ensures long-life operation, due to lower running temperatures and high-reliability safety features.

External current limiting resistors are not required, and far fewer external components are needed as they have been included inside the module. This results in simpler and smaller designs overall.
