LCR Electronics is releasing two new analogue brushless DC motor controls for use in three-phase brushless DC motors typically found in high-reliability environments. The cost-effective boards feature simple user interfaces, making the EC105 and low-voltage EC107 useful for portable and space-constrained applications such as commercial tools, appliances and small traction systems.
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 use a trapezoidal two-quadrant control technique and include softstart, resettable overload detection and an optional coating for humid or wet environments. The analogue brushless DC motor control systems operate at a temperature range of 0 to +85 degrees C. Introduction of a four-quadrant control version is planned for late 2009.
While the EC105 has an input of 120/240V AC, a 3A maximum load current (upgradable to a maximum of 20A) and an output of 150/300V DC, the EC107 has an input of 12/24V DC and a load current of 5A maximum (upgradable to 20A).
Both controls are RoHS-compliant, optionally EMI-compliant and are available with a quick turnaround time to help customers get products to market fast.
Pricing for the EC105 starts at $75 per unit in quantities of 1000; pricing for an EC107 starts at $50 per unit in quantities of 1000. Delivery is typically eight weeks ARO.
