Variable speed control for brushless DC motors

Dart Controls introduces the 700 series DC Brushless Drives – a compact, economical, energy efficient alternative in brushless DC (BLDC) motor control. They are suitable where high speed or quiet operation are desired, combined with a BLDC motor to eliminate brush wear. With models available for 12VDC to 48VDC voltage supply and 5ADC to 20 ADC current, in open or closed loop designs, the 700 series fits a wide range of applications. Space saving design allows them to fit in a tight footprint. Open chassis or NEMS 4/4X enclosed styles are available, along with panel mount design (BLM series). All Commutrol series models are designed for motors with Hall sensors included.

Feature rich 700 series DCBL drives feature contactor-less reversing, 5KΩ speed pot kit, low power inhibit circuit for motor start/stop and overload capacity of 150% to 200% for one minute. Each unit features run/stop output, supply voltage, and Fault LEDs. With robust operational features and quiet operation – high frequency switching, the 700 series Commutrol series is for use in medical equipment, conveyor ovens, solar applications, fans, pumps, suction devices, and more.

Designed to operate in ambient temperatures from -10°C to 45°C (14°F to 113°F), with high efficiency-low power loss, these robust units offer a long service life for drives and motors. Open or closed loop models available; closed loop models allow ±1/2% base speed regulation with no encoder required.

Developed specifically for OEM applications, the RoHS compliant 700 series delivers maximum flexibility and value. All 700 series models are manufactured by Dart Controls, a manufacturer of variable speed motor drives, controls, and accessories for electric motors – and are available through their nationwide distribution network. Dart products are 100% Made in the USA – designed, manufactured, tested, and shipped from their Zionsville, Indiana headquarters and available through a nationwide network of distributors – providing cost advantages in times of tariffs and uncertainty. With over 100 years’ combined motor and control expertise, Dart engineers are available to discuss applications and make recommendations before and after the sale.
