New DPM Brushless 33 and 42mm.

These new Brushless motors with integrated hall sensor provides very good performances in small volume. The high energy permanent magnet used in our BLDC motors produce a very high efficiency and acceleration with peak torque that can reach 0,45 Nm.
Their linear torque curve allows them to be used in a very large speed range up to 12.000 rpm.
Brushless motors are in general cool running, which has been found to be a definite benefit in medical and hand tools application where these specific size are widely used.
Long Lifetime and high reliability complete the advantages of the new 33BL and 42RBL.
As for the other DPM Brushless motor sizes also these new products are available in different lengths and can be easily customized to match specific customer requests.
Optional like Encoders, Gearboxes, brakes and integrated driver are also available.
DPM Brushless range include now motors from 22 mm diameter up to 86mm with a torque range from 8 mNm to 2,1 Nm.

What is a step motor?

A stepper motor driver is a motor which convert bipolar or monopolar input pulses into proportional steps (position).

What are the advantages of using step motor drivers?

1. Drive speed can be easily determined and controlled by remembering that speed equals steps per revolution divided by pulse rate.

2. A step motor can make fine incremental moves.

3. A step motor doesn't require encoder feed back ( Open loop ).

4. Non-cumulative positioning error.

5. Excellent low speed/high torque characteristics without gear reduction.

6. Holding torque of the step motor can be used to hold loads in stationary position without over heating.

7. Ability to operate on a wide speed range
