Magnetic Couplings & Clutches

Magnetic couplings and clutches smoothly and cost-effectively transmit torque with servo-quality overload protection for nearly any type of industrial manufacturing. Benefits/features include:

	Smooth disengagement, even during high torque
	Easy to assemble and adjust
	High stiffness and low inertia
	Exact transmission of the rotational movement even under extreme temperatures and environments
	Use for unique applications requiring reliability, precision, power and repeatability within the same package
	All magnetic clutches are available in full stainless steel

Synchronous Magnetic Clutches
Provide servo-quality overload protection for manufacturing applications requiring frequent high-torque operations.

Available in shaft-to-shaft, disk or shaft-flange styles, these clutches transmit force with no physical contact. They are even capable of safely transmitting torque through a wall. High-torque transmission is accomplished by the synchronous clutches’ permanent-magnet design, which consists of two multiple-pole magnetic cylinders. Torque is produced by the magnetic field across the air gap between the two cylinders.

Typical Applications

Magnetic Clutches

MKD Permanent-Magnet Synchronous Couplings - Collet Type

MKD series clutches transmit torque from 10 lb-in (1.2 Nm) to
2655 lb-in (300 Nm) on shafts from 0.125" (3 mm) to 1.575" (40 mm).
Following an overload, the clutch disengages and slips. This reduces the risk of damage to connected equipment.

MDC Permanent-Magnet Synchronous Couplings - Disc Type

MDC series clutches transmit torque from 18 lb-in (2 Nm) to
265 lb-in (30 Nm) on shafts from 0.25" (6 mm) to 1.125" (28 mm).
Following an overload, these clutches disengage and slip, even when used with a barrier, thus reducing the risk of damage to connected equipment.

MSV Permanent-Magnet Synchronous Couplings - Cylindrical Type

MSV series clutches transmit torque from 443 lb-in (50 Nm) to
8851 lb-in (1000 Nm) on shafts from 0.75" (20 mm) to 2.6" (65 mm). These barrier-type clutches -- which can be hermetically sealed -- slip when overloaded, thus reducing the risk to connected chemical pumps or other equipment.

Hysteresis Magnetic Clutches
These maintenance-free magnetic safety clutches are designed as two parts that nestle together, but without physical contact. The clutches are available in shaft-to-shaft, disk or shaft-flange styles.

Hysteresis clutches offer extremely smooth constant torque, available over the motor’s entire speed range. The torque is produced by the magnetic field across the air gap between the two sections of the clutch. In case of overload, hysteresis magnetic clutches disengage without the abrasion and jerks that limit the wear life of conventional mechanical-type clutches.

HKD Permanent-Magnet Hysteresis Couplings - Collet Type

HKD series clutches transmit torque from 0.9 lb-in (0.1 Nm) to 80 lb-in (9.0 Nm) on shafts from 0.125" (3 mm) to 1.575" (40 mm). Following an overload, the torque transmitted remains at the rated torque level. The overload energy is converted into heat which is safely dissipated.

HSV Permanent-Magnet Hysteresis Clutches - Flange Type

**Special** HSV Bottle Capping Clutch - Flange Type

HSV series clutches transmit torque from 0.9 lb-in (0.1 Nm) to 36 lb-in (4.0 Nm). These special clutches are ideal for applications such as bottle capping, unwind/rewind, brakes, and test equipment that require constant slipping with some torque.
