Mechanical dynamometer 2WD - BPA-2R S

single-phase motor

Description
The S series is a roller dynamometer designed for standard car workshops and test lanes. It features knurled rollers (CNC finish) for maximum traction and highly accurate measurements. The model BPA-2R S is a 2WD configuration, upgradable to 4WD, and is used by electric vehicle manufacturers.

Mechanical features:

• Roller diameter: 240 mm
• Roller width: 660 mm
• Balance quality grade: G 2.5
• All mechanics laser aligned
• Overall dimensions (mechanical): 1132 x 3130 x 360 mm
• Max weight per axle: 2,000 kg

Performances:

• Maximum speed: 250 km/h
• Maximum measurable power: 400 HP

Power supply:

• Dyno voltage: single phase 230 VAC
• Fan cooling system voltage: 3/N/PE 400 VAC
• Frequency: 50 Hz
• Fuses: 16 A
• Compressed air: 6 bar

Advantages:

• Faster repair process through precise diagnosis
• Use of existing workshop instruments (diagnostic tools, gas analyzer)
• Avoids risks associated with road tests (traffic, accidents, fines)
• Certified results for performance verification
• Improves accessory sales by verifying results (exhausts, ECU, etc.)
• Supports used-vehicle sales via engine health certification
• Vehicle checks before second-hand trades
• Suitable for rental for tests and technical checks

Measuring program:

• Transmission verification (clutch slippage)
• Power step test
• Power sweep test
• Cooling system check (radiator, fan sensor, thermostatic valve)
• Diagnosis by gas analyzer under load
• Vehicle test with constant speed
• Vehicle test with constant force
• Vehicle test with constant load
• Road simulation (slope, drag resistance, weight)
• Vehicle test with constant RPM
• Durability tests
• Engine mapping across all RPM
• Diagnosis by scantool during road simulation

Standard features

• Eddy currents brake, 4 rollers knurled over the entire width (CNC)
• Pneumatic vehicle lifter with integrated rollers lock
• Fully functional management software

Optional features

• Double ventilation system on wheels — 6 kW, flow 44,000 m3/h
• Single ventilation system on wheels — 3 kW, flow 22,000 m3/h
• Lambda kit: 5-wire wideband lambda probe and controller
• Boost pressure input 0 ÷ 2.5 bar (±0.035 bar) — requires external meteo sensor box
• Lambda input for external vehicle lambda probe (requires meteo sensor box)
• High-width aluminum loading ramps (for floor installation)
• Heavy-duty computer trolley (movable)
• Proportional ventilation speed control (fan speed vs rollers speed)
• Infrared remote control from vehicle cockpit
• Roller covers for protection when idle
• Personal computer and display
• Safety equipment: side barriers with logo panels, anchoring ratchets, high-attenuation ear muffs
• OBDII parameters reading and DTC deletion without extra hardware
