General Purpose drives designed for use with Permanent Magnet or Shunt wound DC motors. It is important that the proper . Motor or control damage could result from peak voltages. Line fuses are preinstalled on all cased drives.
Such SCR controls get their name from the silicon controlled rectifiers (SCRs ) they use to convert the AC current supplied by the power company to DC.
However, the proper voltage motor should be selected for use with the power supply input, i.
DC motors for 1volt input or 1volt motors for 2volt input service.
LEESON Speedmaster DC Control information. Specifications are subject to change without notice. Dual voltage capable on most designs – see . Leeson Electric Motors , Free shipping on all Leeson Controls shipped direct from Leeson Warehouse Only applies to motors shipped to the Continental USA.
Leeson Speedmaster DC controls are general purpose drives designed for use with permanent magnet type direct current motors. Verify that the motor is wired correctly.
No output power from controller. Measure voltage coming from the controller. Motor damaged and the fan guard is contacting the cooling fan.
Motor is damaged and the armature is rubbing against the magnets. Disassemble motor and see if the . These are typically used with SCR controllers that require adjustable speed and constant torque throughout the speed range . Has field supply for shunt wound motor control.
Open chassis unit is typically used for building into equipment, machinery or existing enclosures. For additional information or to order please . SCR ( thyristor) controller in applications requiring adjustable speed and constant torque. Install the output motor leads in their own rigid steel conduit. Low voltage DC control wiring and 1Vac control wiring should be run in separate conduits.
Make sure that all grounds are tightly connecte and properly earth grounded.
NOTE: If multiple VFDs are mounted . THIS BOOK COVERS LOW VOLTAGE CONTROL CATALOG NUMBERS. HP Permanent Magnet DC motors are typically used with and SCR (thyristor) controller in applications requiring adjustable speed and constant torque throughout the speed range. Leeson DC motors are typically used with an SCR controller in applications requiring adjustable speed and constant torque throughout the speed range.
They also offer Washdown and IEC DC motors as well as DC Gearmotors.
