High performance synchronous electric motor
max. 3.7 Nm, 3 000 rpm, 1 160 W | HLR 37 ENGEL

The High-Power Three-phase synchronous Motors of series HLR 37 are fitted with a
3-phase concentrated stator-winding system. The 6-pole rotor-magnet system is made
of high-grade Neodymium Iron Boron.
The motors have a sinusoidal Back EMF.
The position information of the rotor, a required tacho voltage and pulses for a closed
loop position control will be generated using the integrated brushless pancake-resolver.
To avoid thermal overload a PTC resistor is embedded in the stator winding.
Types HLR 3760 and HLR 37100 are also available with integrated parking brake.

Features:
High acceleration because of small moments of inertia
Large peak torques because of high allowable pulse currents
Maintenance-free operation due to brushless design - mechanical life cycle only depends on bearing and its lubrication
High overload range due to high thermal time constant and good dissipationof the powerlosses occurred in the stator
The very compact design allowing high power output in a very small volume
Robust mechanical structure with aluminium cast housing
