Premotec has expanded its range of BLDC58 series brushless DC motors with integrated electronics.
Premotec has expanded its range of BLDC58 series brushless DC motors with integrated electronics.
After launching versions with increased torque, higher speed and reduced length, the next requirement from the market was a version with active braking.
This additional function is now available.
Product features include starting and stopping within 0.5s, short reversal time and improved speed loop, with excellent stability of rotational speed under changing load conditions.
The lowest stable motor running speed is 70rev/min.
Torque up to 25Nm is possible when combined with spur or planetary gearheads.
Integrated commutation electronics with speed control loop are contained in a completely closed envelope.
Nominal voltage is 24V, nominal speed is 3100rev/min and maximum motor torque is 170mNm.
A second version features an improved dynamic range with PWM input and improved speed stability for peristaltic pump applications.
Combined with a low noise gearhead with a ratio of 27:1, this unit gives a shaft speed of 2.5 to 115rev/min.
This version will be available in the second half of 2002.
