Following its successful market launch in the “42 mm class,” Gerdt Seefrid GmbH is continuously expanding its product range of BLDC drives and matching controllers. The Bad Vilbel-based company will be adding 57 mm diameter BLDC motors to its portfolio next year. These drives are available both without gearboxes and in combination with worm gears.
The BMC 300H controller for BLDC motors with Hall sensors has been available from stock since the second quarter of 2015. With five digital inputs, five integrated potentiometers for setpoint inputs, two relay outputs, a supply voltage output for sensors, and a CANopen interface, Seefrid’s multi-talented device offers a cost-effective way to control brushless DC motors with up to 10 A continuous current. Thanks to its diverse functions, the controller can be used to solve small control tasks even without the use of a higher-level PLC. The BMC 50H BLDC controller is available for motor currents up to 2.5 A and simple applications. This controller also features a good price-performance ratio and high availability.
