Sprint Electric PL DC Drives for High-Performance Industrial Motor Control
Quick Answer: Sprint Electric PL DC drives are high-performance, fully digital, 2-quadrant DC motor drives designed for accurate speed and torque control in demanding industrial applications. The PL range covers ratings from 5 kW to 315 kW in Industrial Motor Warehouse’s current UK collection, with models from 12 A to 750 A and three-phase configurations.
For applications needing regenerative braking or four-quadrant operation, the closely related Sprint Electric PLX drive range extends the technology into higher-performance 4Q DC motor control.
Sprint Electric DC Drives
Industrial DC motors remain crucial in UK plants where high starting torque, controlled acceleration, stable speed regulation, and repeatable torque performance are more important than simply replacing an existing DC system with an AC inverter.
The Sprint Electric PL drive is engineered for this type of application. As a digital DC motor controller, it provides closed-loop control and programmable operating parameters while retaining the characteristics that make separately excited and permanent-magnet DC motors useful in demanding machinery.
Industrial Motor Warehouse supplies a broad selection of Sprint PL DC drive models, from compact 5 kW units through high-power 315 kW versions. The current collection includes 2-quadrant, three-phase models such as PL5, PL10, PL15, PL20, PL30, PL40, PL50, PL65, PL85, PL115, PL185, PL225, PL265, PL275 and PL315.
Why Choose a Sprint Electric PL Drive?
The selection of a DC Drive should be based on the complete motor-control requirement rather than the kW rating of the drive alone. Armature current, field current, motor voltage, feedback method, acceleration requirements, braking requirements, and load inertia all influence the correct selection.
A Sprint Electric digital DC drive provides various advantages for industrial installations:
- Precise speed and torque control regulation
- Controlled acceleration and deceleration
- Digital parameterisation and commissioning
- 2-quadrant operation for applications requiring motoring in one direction
- Three-phase input configurations
- High-current options for demanding DC motors
- Compact designs for control-panel integration
- Protection functions designed for industrial motor-drive applications
PL DC Drive Rating and Selection
Choosing a DC drive by motor horsepower alone can lead to an incorrectly sized system. The drive should be matched to the motor’s armature voltage, continuous armature current, field requirements, and operating duty.
| PL Model | Output Power | Armature Current | Configuration |
|---|---|---|---|
| PL5 | 5 kW | 12 A | 2Q, three-phase |
| PL10 | 10 kW | 24 A | 2Q, three-phase |
| PL20 | 20 kW | 51 A | 2Q, three-phase |
| PL40 | 40 kW | 99 A | 2Q, three-phase |
| PL65 | 65 kW | 155 A | 2Q, three-phase |
| PL115 | 115 kW | 270 A | 2Q, three-phase |
| PL185 | 185 kW | 430 A | 2Q, three-phase |
| PL225 | 225 kW | 530 A | 2Q, three-phase |
| PL265 | 265 kW | 630 A | 2Q, three-phase |
| PL315 | 315 kW | 750 A | 2Q, three-phase |
Sprint Electric DC Drive Technology
The shift from analogue to digital DC control has significantly improved the flexibility of industrial drive systems.
A Sprint Electric digital DC drive allows operating parameters to be configured electronically rather than relying exclusively on analogue potentiometers and adjustments in the hardware. This can simplify commissioning and make it easier for engineers to reproduce settings across machines.
Sprint Electric provides technical documentation for PL/PLX systems, including product manuals, serial communications documentation, and fieldbus documentation.
PL vs. PLX: Which One Is More Suitable?
One of the most important decisions is whether the application needs 2-quadrant or 4-quadrant control.
| Feature | Sprint PL | Sprint PLX |
|---|---|---|
| Drive type | Digital DC drive | Digital DC drive |
| Operation | 2-quadrant | 4-quadrant |
| Motor direction | Single direction | Forward and reverse |
| Regeneration | Application dependent | Fully regenerative |
| Typical use | Single-direction machinery | Reversing/regenerative applications |
| High-power applications | Yes | Yes |
| Industrial automation | Yes | Yes |
Where Are Sprint PL DC Drives Used?
Manufacturing and Production Lines
DC motors are still found throughout older and modern production equipment where accurate speed and torque control is required. A digital DC drive can provide a practical control upgrade without necessarily replacing the motor itself.
Printing and Paper Machinery
Printing, coating, winding, and paper-processing equipment can need tightly controlled motor speed and torque. The response characteristics of a DC motor and digital drive combination can make it suitable for such applications.
Conveyors and Material Handling
For conveyor systems, controlled acceleration helps reduce mechanical shock to belts, couplings, and gearboxes. The correct drive configuration can also provide stable speed control under changing loads.
Extrusion and Process Machinery
Extruders and other process machines often need consistent motor torque and speed. Therefore, choosing the drive according to regular current and overload requirements is critical.
Retrofit and Legacy DC Systems
DC drive replacements are one of the strongest use cases for the PL range. UK manufacturers frequently have machines that remain mechanically productive but contain obsolete or difficult-to-source drive electronics.
Replacing the drive rather than the entire motor system can reduce project scope, minimise mechanical modification, and also shorten downtime, provided the existing motor, feedback system, and electrical architecture remain suitable.
Key Factors When Selecting a Sprint PL DC Drive
Before ordering a Sprint Electric PL drive, it is advisable to check the following motor and application information:
- Motor Armature Current
Confirm the DC armature voltage matches the drive’s available output range. - Armature Current
Continuous and overload current requirements should be assessed against the drive rating. - Field Requirements
Check the motor’s field voltage and current, particularly where a separately excited field is used. - Feedback Device
Determine whether the existing motor uses an encoder, tachogenerator, or another feedback arrangement. - Quadrant Operation
If the machine only demands forward motoring and controlled braking, 2Q may be appropriate. If it needs frequent reversal and regenerative operation, consider a PLX 4Q solution. - Supply Voltage
Confirm the available three-phase supply and any site-specific requirements before selecting the drive variant. - Duty Cycle and Overload
A drive should not be selected mainly from the motor’s nominal kW. Peak loads, acceleration time, cyclic operation, and thermal conditions should also be considered.
