EC / BLDC Motors
2
EC motors are also called brushless DC motors. Their
construction is equivalent to the construction of a three-pha-
se synchronous motor with permanent magnet rotor. There
are no service life limited parts (except for ball bearings), like
for example the carbon brush for DC motors. However, the
control behavior and characteristic curve of EC motors are
similar to those of a DC motor. By means of the simple and
robust design and the low requirements of control electro-
nics this motor type can be used with a simplified frequency
converter with block commutation. On the inside, a polymer-
bonded neodymium magnet ring is employed. With its com-
pact magnet ring it is particularly suitable for higher torques.
Compared to a common asynchronous motor an EC motor is characterized by a higher power density. In combination with
a rotor position detection on Hall basis (RLE) it can also be used as variable-speed drive.
The EC series of Heidrive GmbH consists of three sizes with different lengths and is covering a power range from 35 W
to 220 W. This corresponds to a nominal torque of 0.1 Nm to 0.7 Nm. The motors specified here have a triple overload
capacity.

The construction of BLDC motors is very similar to the
construction of the previously described EC motors. Ho-
wever, here a highly efficient permanent magnet rotor is used.
The utilized sintered rare earth magnet segments (NdFeB)
entail a higher degree of efficiency and thus a higher power
output. The higher power density of this motor type enables
the realization of a more compact size. For BLDC motors a
high-order and very robust encoder system on Hall basis
(HES) is employed. BLDC motors are particularly suitable for
dynamic drives in 4 Q operation.
The BLDC series of Heidrive GmbH consists of two sizes with two lengths in each case and is covering a power range
from 200 W to 800 W. This corresponds to a nominal torque from 0.65 Nm to 2.55 Nm. The motors specified here have
a fourfold overload capacity.

In their standard version, all EC motors are equipped with a rotor position detection (RLE). Optionally the motors of
type EC07 (type 306) are also available with a HES encoder.
In the standard version of the entire BLDC motor series the HES encoder is installed.
Overview of encoders that can be used:
