50% More Power and Even More Control
Premotec has expanded its brushless DC motor family with the introduction of the new 12-watt BL48, 4-wire version.
Premotec doubles rating of BL58 brushless DC motor
Premotec has once again expanded its range of brushless DC motors with the introduction of a new 70-watt motor at double the rating of its original BL58 motor.
Exhibiting very low EMI, the BL48 is supplied with fully integrated drive electronics in 12 and 24 volts versions.
Apart from the normal two wires for supply of power, each motor is provided with two extra wires.
One enables the user to control motor speed over a wider range, the other provides a motor speed signal enabling use within a closed loop control system.
A 12-pole external rotor and 9-coil iron core stator within a motor diameter of only 54 mm and length of 30 mm produce 8 watts output power.
Smooth, constant speeds up to 4300 rpm are ensured by the external rotor and service-free life in excess of 20,000 hours can be obtained due to the use of high quality ball bearings and the absence of mechanical brushes.
Further integration into customer applications can be provided through combination with a wide range of long-life spur and planetary gearboxes, custom mounting flanges, alternative shaft configurations, and the addition of customer- specified drive components.
The flexible, highly reliable but economic nature of the BL48 make it the ideal drive solution in a wide variety of customer applications such as laboratory stirrers, medical and industrial pumps, H.V.A.C.
