LCR Electronics' analog brushless DC motor controls are designed for high-reliability applications

LCR Electronics has released two analog brushless DC motor controls that are well suited for use in three-phase brushless DC motors typically found in high-reliability environments.

Each board features a potentiometer for speed command, a toggle switch for direction and a tact switch for fault reset, which provides precise, variable control of motor speed using the motor’s hall effect sensors for feedback.

The EC105 and EC107 from LCR Electronics use a trapezoidal two-quadrant control technique and include soft start, resettable overload detection, as well as an optional coating for humid or wet environments. The analog brushless DC motor control systems operate at a temperature range of 0°C to 85°C.

The EC105 has an input of 120/240 VAC and a 3 A maximum load current, which is upgradable to a maximum of 20 A. Its output is 150/300 VDC. The EC107 has an input of 12/24 VDC and a load current of 5 A maximum, which is also upgradable to a maximum of 20 A.
