A new encoderless, field-oriented control method (vector control) from KEB Automation provides users (maximum torque per ampere) with control over the entire speed range. This benefits servo drives for positioning applications, for example, where high concentricity is required, even at the lowest speeds.
Carlo Gavazzi has launched the RVBS variable frequency drive for speed control applications such as pumps, fans, conveyors, compressors and HVAC systems of up to 0.75kW.
Melexis introduces the MLX81334, a motor driver designed to optimise electric vehicles' thermal valves (accurate battery temperature control) and expansion valves (heat pump refrigeration loop). This enables a longer range for EVs.
Performance, pump protection and high-precision control without compromise – all this is provided by the servo pump control function integrated into KEB Automation’s drive controllers. In combination with KEB’s DL4 and TA series servo motors, they can also save energy.
Oriental Motor introduces the BLH2D driver, with dedicated vector control, lower noise and increased control for its BLH series of brushless DC (BLDC) motors.
